Opis:
The article presents the results of studies concerning the selection of the chemical composition of the new ecological copper alloys for fittings. It was analyzed, among other things, the impact of the content of bismuth, aluminum, iron and boron. Their solidification process was characterized on the grounds of thermal and derivative analysis (TDA). Also the microstructure and mechanical properties were analyzed. Casting properties were determined by the castability spiral test. It was found that zinc is an essential component of the tested group of alloys, determining the course of their crystallization, phase composition and microstructure. There was no significant effect from the other elements on the course of crystallization. The obtained results revealed that bismuth is the element of the strongest impact on the castability changes. The formulated alloys surpass the commonly used standardized alloy intended for components of fittings, namely MO59, in terms of casting and mechanical (hardness) properties.

Opis:
The paper presents the results of research on the determination of the effect of pouring temperature on the macrostructure of the castings subjected to complex (surface and volume) modification and double filtration. Tested castings were made of post-production scrap (gating system parts) of IN-713C superalloy. Tests included the evaluation of the number of grains per 1 mm2, mean grain surface area, shape factor and tensile strength. Casting temperature below 1470 °C positively influenced the modification effect. The grains were finer and the mechanical properties increased, especially for castings with thicker walls. On the other hand, manufacture of thin walled castings of high quality require pouring temperature above 1480 °C.

Opis:
The article presents the investigations of 7xxx aluminium alloys performed by the method of thermal and derivational analysis. The studies made it possible to identify the effect of the changes in the Cu concentration, the total Zn and Mg weight concentrations and the Zn/Mg weight concentration ratio on their crystallization process: the cooling as well as the kinetics and dynamics of the thermal process of cooling and crystallization. Metallographic studies were performed on the microstructure of the examined alloys and their HB hardness was measured. The evaluation of the changes was presented in reference to the model alloys EN AW-7003 and EN AW-7010, whose microstructure under the conditions of thermodynamic equilibrium are described by the phase diagrams: Al-Zn-Mg and Al-Zn-Mg-Cu. The performed investigations confirmed that the hardness HB of the examined alloys is mainly determined by the reinforcement of the matrix αAl by the introduced alloy additions and the presence of phases Θ(Al2Cu) and S(Al2CuMg) rich in copper, as well as η(MgZn2), in the examined alloys' microstructure. The increase of the amount of intermetallic phases precipitated in the microstructure of the examined alloys is caused, beside Cu, by the characteristic change of Zn wt. concentration and Mg. It was proposed that the process of one-stage thermal treatment of the examined alloys be introduced at a temperature of up to tJ-20 °C, which will prevent the exceedance of the solidus temperature.

The study discusses the issues connected with the production of thin-walled ceramic slurry in the replicast cs technology. In the ceramic mould production process, a special role is played by the liquid ceramic slurry used to produce the first layer of the mould. The study examines selected technological properties of liquid ceramic slurries used to produce moulds in the replicas cs technology. The ceramic slurries for the tests were prepared based on the binders Ludox Px30 and Sizol 030, enriched with Refracourse flour. The wettability of the pattern's surface by the liquid ceramic slurry and the dependence of the apparent viscosity on the ceramic flour content in the mixture were determined. The wettability of the pattern surface by the liquid ceramic slurry was determined based on the measurement of the wetting angle. The angle was determined by means of an analysis of the computer image obtained with the use of a CDC camera.

The results of estimation of home scrap addition in charge influence on durability and wear of casting instrumentation life in the high-pressure casting technology using the hot chamber machine of alloy of AZ91 are presented. The wear of the following elements of the casting instrumentation so-called "casting set" as: syphon, plunger, sliding-rings, nozzle and injection moulding nozzle was estimated. A wear was estimated quantitative by registering the number of mould injections for different charges to the moment of element damage supervision. A damage had to be at such level that liquidated an element from further exploitation and necessary was an exchange on new or regeneration. In a final result allowed it the detailed determination of durability of the applied rigging elements in dependence on the type of the applied type of melt. It is noticed, that together with the increase of home-scrap participation in the charge wear of pressure machine instrumentation elements increases.

Opis:
In current casting technology of cored, thin walled castings, the modifying coating is applied on the surface of wax pattern and, after the removal of the wax, is transferred to inner mould surface. This way the modification leading to grain refinement occur on the surface of the casting. In thin walled castings the modification effect can also be seen on the other (external) side of the casting. Proper reproduction of details in thin walled castings require high pouring temperature which intensify the chemical reactions on the mould – molten metal interface. This may lead to degradation of the surface of the castings. The core modification process is thought to circumvent this problem. The modifying coating is applied to the surface of the core. The degradation of internal surface of the casting is less relevant. The most important factor in this technology is “trough” modification – obtaining fine grained structure on the surface opposite to the surface reproduced by the core.

Opis:
This work presents the research result of the temperature distribution and the microstructure in certain parts of the field-glass body frame casting made from silumin AlSi9 using the investment casting method in the ceramic mould. It was proved that the highest temperature of the silumin appears in the sprue in which the silumin is in the liquid-solid state, though the process of silumin crystallization in the casting is finished. It was stated that in certain elements of the casting the side opposite to the runner crystallizes and cools fastest. The differences in the rate of crystalline growth and cooling of certain casting elements cause different microstructure in them which can also influence the mechanic properties. It is necessary to state that the temperature of the initial heating of the ceramic mold equal to 60ºC guarantees obtaining of the castings without defects and of little porosity. Incomplete modification of the silumin with strontium causes silica precipitation to appear close to the spherical ones.

Opis:
The paper presents some aspects of the theory and technology of high quality silumin castings in metal molds cooled pointed with water mist stream. The results of the work relate to improvement of the properties of silumin casts by affecting the cooling of the liquid silumin in gravity cast in metal mold and the possibility of controlling the solidification and crystallization of the casting. The high efficiency required from the cooling system is a consequence of an optimal selection of parameters of the generated mist and the maximum use of the phenomenon of water droplets evaporation on the surface of the cooled mold. The study showed that sequential spot cooling with use of water mist, characterized by a wide range of control means and a high maximum heat transfer efficiency, enables to control the flow of heat between the casting and the mold and it allows for a layered solidification leading to the realization of the entire cast solidification in the expected way: directional or simultaneous. Consequently, the results are: improvement of the quality of the castings as a result of the elimination of defects and significant reduction in shrinkage porosity in the casting, an increase of the homogeneity and fineness of the microstructure, about 25% increase in the mechanical properties.

Opis:
Homogeneity of die castings is influenced by wide range of technological parameters as piston velocity in filling chamber of die casting machine, filling time of mould cavity, temperature of cast alloy, temperature of the mould, temperature of filling chamber, surface pressure on alloy during mould filling, final pressure and others. Based on stated parameters it is clear, that main parameters of die casting are filling time of die mould cavity and velocity of the melt in the ingates. Filling time must ensure the complete filling of the mould cavity before solidification process can negatively influence it. Among technological parameters also belong the returning material, which ratio in charge must be constrained according to requirement on final homogeneity of die castings. With the ratio of returning material influenced are the mechanical properties of castings, innerhomogeneity and chemical composition.

Opis:
Technologia wytapianych modeli należy do najstarszych technologii odlewniczych. Historycznie służyła do odlewania narzędzi, broni i ozdób. Model wykonany z wosku pszczelego oblepiano gliną suszono i wypalano. Otrzymywano odlewy o dużej gładkości powierzchni, dokładności i precyzji wykonania ornamentu. Metodą tą odlewano niewielkie kilkugramowe odlewy jak i wielkogabarytowe pomniki. Współcześnie ta technologia jest wykorzystywana w wielu ważnych gałęziach produkcji zarówno artystycznej, jak i przemysłowej. Szczególnie w przemyśle zbrojeniowym, lotniczym, motoryzacyjnym, energetycznym, budowlanym, a nawet kosmicznym. W pracy przedstawiono wyniki badań i eksperymentów, prowadzonych w zakresie technologii odlewnictwa miedzi i stopów miedzi z zastosowaniem metody wytapianych modeli, zarówno w aspekcie historycznym, jak i współczesnej praktyki przemysłowej. Przykładowo przedstawiono analizę wybranych elementów dawnych technologii, form i odlewów wytworzonych w epoce brązu oraz wyniki badań dotyczące aktualnie produkowanych odlewów dla branży energetycznej. Jakość odlewów została oceniona na podstawie przeprowadzonych badań z zakresu mikrostruktury, składu chemicznego, przewodności elektrycznej i zawartości tlenu.
Investment casting technology belongs to the oldest casting techniques. Historically, it was used for casting tools, weapons and ornaments. A model, made from beeswax, was covered in loam, dried and fired. The casts obtained were characterised by high surface smoothness, accuracy and precision of its ornaments. This method was used for relatively small casts as well as for big monuments. Nowadays, this technology is used in many fields of manufacturing, both artistic and industrial, especially in ornaments, aviation, automotive, power, construction and even space industry. This work presents the results of research and experiments conducted in the field of casting technology of copper and copper alloys, applying the investment casting method, both in its historical aspect and modern industrial practice. An exemplary analysis was presented of the chosen elements of the old technologies, moulds and casts, as well as the results of casts made currently for the power industry. The casts quality was evaluated based on the research of their microstructure, chemical composition, electrical conductivity and oxygen content.

The work presents the results of the investigations of the effect of inhibitors coated on the internal walls of a ceramic mould on the quality of the obtained casts made of the AM60 alloy containing additions of chromium and vanadium. In order to reduce the reactivity of magnesium alloy cast by the technology of investment casting with the material of the mould and the ambient atmosphere, solid inhibitors were applied in the form of a mixture of KBF4 and H3BO3 after the stage of mould baking and before the mould’s being filled with the liquid alloy. For the purpose of examining the effect of the inhibitors on the surface quality of the obtained casts, profilometric tests were performed and the basic parameters describing the surface roughness, Ra, Rz and Rm, were determined.

Opis:
The process of creating medical models for experimental tests applying modern Rapid Prototyping methods is presented in the article. Respective Rapid Prototyping methods i.e. JS-PolyJet, Selective Laser Sintering (SLS), ProJet and Vacuum Casting (VS) methods are also characterised. The possibilities of using the above in model research and especially in photoelastic research on the examples of human skull top part and a fragment of syndesmosis of the skull are discussed. Rapid Prototyping and Rapid Tooling methods together with computer aided systems CAD/CAM make it possible to carry out numerical analysis and experimental tests on models of very complicated inside and outside shapes. RP techniques allow for fabricating medical models of a tissue structure of human skeleton bones. In case of photoelastic tests, when examined medical object can be destructed, RT techniques and precisely Vacuum Casting method allows for making medical models with reasonable prices and quantities adequate for experimental aims. There is a possibility of analyzing much bigger range of cases of loading regardless of the costs of experiment. Therefore applying Rapid Prototyping techniques for fabricating medical models allows for extending the possible applications of experimental tests in medicine.
W artykule przedstawiono proces tworzenia modeli medycznych przeznaczonych do badań eksperymentalnych z wykorzystaniem nowoczesnych metod szybkiego prototypowania. Scharakteryzowano wybrane metody Rapid Prototyping począwszy od JS – PolyJet, SLS, ProJet, a skończywszy na metodzie odlewania próżniowego Vacuum Casting. Omówiono możliwości ich wykorzystania w badaniach modelowych, a w szczególności w badaniach elastooptycznych, na przykładzie górnej części czaszki i fragmentu więzozrostu czaszkowego. Metody szybkiego prototypowania RP i RT z jednoczesnym wykorzystaniem komputerowych systemów wspomagania CAD/CAM pozwalają na przeprowadzenie analizy numerycznej jak i badań eksperymentalnych na modelach o bardzo skomplikowanych kształtach wewnętrznych jak i zewnętrznych. Techniki RP umożliwiają wykonanie modeli medycznych z dokładnym odwzorowaniem kształtu analizowanych elementów szkieletu kostnego. W przypadku badań elastooptycznych, gdzie konieczne jest uszkodzenie badanych modeli medycznych, techniki RT oraz techniki VC, umożliwiają szybkie ich wykonanie w rozsądnych cenach i w ilości wystarczającej do badań. Dzięki temu istnieje możliwość przeanalizowania znacznie rozszerzonego zakresu przypadków obciążania przy ograniczeniu kosztów badań. Zastosowanie technik szybkiego prototypowania do wykonywania modeli medycznych rozszerza możliwości badań eksperymentalnych w medycynie.
