Opis:
An analysis has been carried out of the influence of annealing time at the preheating temperature of 650 °C on the change in hardness and alloy structure of lamellar graphite cast iron in the working as well as in the laboratory conditions. This preheat temperature is common during reclaiming welding of castings with complex shapes. The changes in unalloyed cast iron EN-GJL 200 to EN-GJL 300 according to ISO 1690 standard and cast iron with low amount of elements such as Sn, Cu, Cr, and Mo and their combinations were assessed. It was found that the cast iron of higher strength grades has better hardness and structural stability. Cast iron alloyed with chromium or its combinations has the highest stability. In unalloyed cast iron, a partial degradation of pearlite occurs; in alloyed cast iron the structural changes are not conclusive.

Opis:
The paper discusses the problems related to cast iron brake rotors in the context of their hardness, which is one of the fundamental mechanical properties of these components. This property fundamentally determines the resistance to the wear processes occurring at the contact of the working surface of the rotor with the brake pad. In order to ensure a proper braking process, the manufacturer must appropriately select the friction pair in terms of the hardness of the mating components and guarantee the constant hardness of each and every manufactured brake rotor. The research presented in the paper was conducted on a selected group of brake rotors. The average hardness of the investigated group of a given type and given manufacturer was ascertained by calculating the spread of the hardness results and checking whether the differences (and what type of differences) occur for newly manufactured and retailed rotors.
W artykule poruszono problematykę związaną z żeliwnymi tarczami hamulcowymi w kontekście jednej z podstawowych właściwości mechanicznych tych elementów, tj. twardości. Właściwością ta w sposób zasadniczy determinuje odporność na procesy zużyciowe zachodzące na styku powierzchnia robocza tarczy hamulcowej a powierzchnia okładziny klocka hamulcowego. Biorąc pod uwagę właściwy przebieg procesu hamowania, ważny jest odpowiedni dobór pary ciernej w kontekście twardości, ale także utrzymanie stałej twardości każdej z wyprodukowanych przez producenta tarcz. Przedstawione w artykule badania prowadzono na wybranej grupie tarcz hamulcowych, ustalając średnią twardość badanej grupy tarcz hamulcowych określonego rodzaju i producenta, obliczając rozrzut wyników twardości oraz sprawdzając, czy i jakie różnice w twardości tarcz hamulcowych występują dla tarcz bezpośrednio po wyprodukowaniu i przekazaniu do sprzedaży.

Opis:
The article presents the results of analysis of the chemical composition, hardness, microstructure and toughness of selected structural materials. The focus is on the results of impact tests carried out on the 40H steel quenched and tempered at three different temperatures, on grey cast iron used in industrial practice (cast material for brake drums) and on ADI, all of them being considered representatives of the group of materials commonly used in the production of structural elements and finished products, including items for use in the automotive industry. The impact tests were performed at a reduced temperature (-20°C), at room temperature (20°C) and at elevated temperature (150°C), comparing the results obtained with the microstructure of materials tested. It has been shown that in the case of steel, the smallest changes in microstructure cause changes in toughness, while the effect of tempering temperature is in this case of secondary importance. It was also proved that under the conditions of ambient temperature and reduced temperature, better results were obtained for ADI. At elevated temperature, better results were obtained for grey iron castings.

Opis:
In the order to increase the resistance to the friction wear of machine parts appropriate surface treatment application is needed. The aim of presented research was to evaluate the laser alloying with silicon nitride effects obtained in the surface layer of nodular iron and to select the laser treatment parameters that should be appropriate for the treatment of the one of the engine parts, which is a rocker arm. After implementation of silicon nitride into the nodular iron surface layer using laser heating, a uniform, fine, dendritic microstructure similar to the hardened white cast of the allayed zone was created in all performed variants. This microstructure resulted in at least 4-times higher hardness in comparison to the core material. The hardness and the alloyed zone dimensions were dependent on the laser heat treatment variant. The laser beam power density of 41 W/mm2 and its velocity of 2.8 mm/s were selected for the treatment of the rocker arm. It was caused by the effects obtained in the surface layer. With these parameters, it was possible to achieve the hardness of 1300 HV0.1 and the width of the alloying zone of over 4 mm, which is enough to strengthen the surface area of the rocker arm most exposed to the tribological wear.
W celu zwiększenia odporności na zużycie w wyniku tarcia części maszyn potrzebna jest ich odpowiednia obróbka powierzchniowa. Celem prezentowanych badań była ocena efektów stopowania laserowego azotkiem krzemu uzyskanych w warstwie wierzchniej żeliwa sferoidalnego oraz dobór parametrów obróbki laserowej, które powinny być odpowiednie do obróbki jednej z części silnika pojazdu, jakim jest dźwigienka zaworowa. W wyniku wprowadzenia azotku krzemu do warstwy wierzchniej żeliwa sferoidalnego za pomocą nagrzewania laserowego we wszystkich przeprowadzonych wariantach wytworzona została jednorodna, drobnoziarnista i dendrytyczna mikrostruktura o charakterze zbliżonym do zahartowanego żeliwa białego. Efektem takiej mikrostruktury było uzyskanie przynajmniej 4-krotnego zwiększenia twardości w porównaniu z twardością materiału rdzenia. Twardość i wielkość uzyskanej strefy stopowanej zależały od zastosowanego wariantu laserowej obróbki cieplnej. Do obróbki dźwigienki zaworowej wybrano gęstość mocy wiązki laserowej równej 41 W/mm2&enspi jej prędkości 2,8 mm/s. Było to spowodowane tym, że w przypadku takich parametrów możliwe było uzyskanie twardości 1300 HV0.1 i szerokości strefy stopowanej ponad 4 mm, co jest wystarczające do umocnienia najbardziej narażonego na zużycie tribologiczne obszaru powierzchni dźwigienki zaworowej.

Opis:
Though normal air cooling and green sand mold-casted gray iron convey an essentially pearlitic matrix, ferritic gray iron is used in some electro-mechanical applications to have better magnetic properties, ductility, and low hardness. Conventionally, to produce ferritic gray iron, foundryman initially produces pearlitic gray iron, then it is carried through a long annealing cycle process for ferritic transformation. This experiment is conducted to eliminate the long annealing cycle from the conventional process. A process is developed to produce as-cast ferritic gray cast iron by air cooling in the green sand mold. In this experiment, Si content is kept high, but Mn content is kept low based on sulfur content; a unique thermodynamic process is established for decreasing the Mn content from the melt. After a successful preconditioning and optimum foundry return charging, the melt is specially inoculated, and metal is poured into the green sand mold. An extra feeder is added for slowing down the cooling rate where casting thickness is around 15mm. Finally, hardness and metallographic images are observed for final confirmation of the ferritic matrix.

The paper presents results of Ti-addition to High Chromium Cast Iron (HCCI) on the structure and selected mechanical properties. For this study casted two sets of cylinders with dimensions ø20 mm, ø15 mm x 250 mm, for the High Chromium Cast Iron (HCCI) and with the 4% by mass Ti-addition. Melts were performed in the induction furnace crucible capacity of 15 kg. During the heats the cup with installed S type thermocouple was poured to record the cooling curves. The cylinders were subjected to the static bending strength test. Samples for the test microstructure and Rockwell hardness were cut from the cylinders. The study shows that the addition of titanium had an impact on the structure and thus the properties of High Chromium Cast Iron (HCCI). In subsequent studies, through an appropriate choice of chemical composition and proper process control, it is planned to obtain in the structure the titanium carbides TiC and chromium carbides with type (Cr, Fe)7C3.

Opis:
Żeliwo wysokochromowe jest powszechnie stosowanym materiałem w przemyśle górniczym i mineralnym, gdzie wymagana jest duża odporność na zużycie ścierne. Swoje dobre właściwości zawdzięcza obecności w mikrostrukturze twardych węglików. Żeliwo chromowe poddawane hartowaniu ma w praktyce osnowę austenityczną, austenityczno-perlityczną lub perlityczną. Istotnym procesem w czasie obróbki cieplnej jest tzw. destabilizacja austenitu, jest on ważny ponieważ dopiero po jego zajściu może nastąpić przemiana martenzytyczna. W zależności od szybkości chłodzenia, które następuje po procesie destabilizacji austenitu, może powstać perlit, bainit i martenzyt. Przeprowadzone badania dotyczyły określenia wpływu szybkości chłodzenia odlewów z żeliwa wysokochromowego po obróbce cieplnej, na mikrostrukturę i twardość. Badaniu zostało poddane żeliwo wysokochromowe o zawartości 27%Cr i 2,7%C. Przeprowadzono zabieg hartowania z temperatury 950 °C w czasie 4h, następnie odlewy poddano trzem wariantom chłodzenia – w wodzie, w kąpieli solnej i na powietrzu. Zbadano i porównano mikrostrukturę oraz twardość odlewów dla różnych wariantów chłodzenia.
High Chromium Cast Iron (HCCI) is widely use in mining and mineral industry, where abrasive resistance is a principal requirement. Its good properties thanks to the hard eutectic carbides occurring in the microstructure. The effect of heat treatment on HCCI was a subject of many research. High Chromium Cast Iron have an austenitic, austenitic-pearlitic or pearlitic matrix. An important process during the heat treatment is austenite destabilization, thus until after it conduct the martensitic transformation can occur. Depending on the cooling rate that follows the process of destabilization of austenite, perlite, bainite and martensite may form. The present work, aimed at studying the influence of cooling rate after heat treatment, on the microstructure and hardness. The study were carry out on samples of High Chromium Cast Iron containing 27%Cr i 2,7%C. Samples were subjected to the tempering treatment at the temperature of 950°C for 4 hours and three variants of cooling – in water, in a salt bath and on air. Examined and compared the microstructure and hardness of castings for different variants of cooling.

Opis:
The present work, presented the study of effect of different inoculants on impact toughness in High Chromium Cast Iron. The molds were pouring in industrial conditions and samples were tested in laboratory in Faculty of Foundry Engineering at AGH. Seven samples were tested - one reference sample, three with different addition of Fe-Ti, and three with different addition of Al. The samples were subjected to impact toughness on Charpy hammer and the hardness test. The presented investigations indicate that for the each inoculant there is an optimal addition at which the sample obtained the highest value of impact toughness. For the Fe-Ti it is 0.66% and for Al is 0.17%. Of all the examined inoculants best results were obtained at a dose of 0.66% Fe-Ti. Titanium is a well-known as a good modifier but very interesting results gives the aluminum. Comparing the results obtained for the Fe-Ti and Al can be seen that in the case of aluminum hardness is more stable. The hardness of all samples is around 40-45 HRC, which is not high for this type of cast iron. Therefore, in future studies it is planned to carry out the heat treatment procedure that may improves hardness.

The paper presents an innovative method of creating the layered castings. The innovation relies on application the 3D printing insert obtaining in SLM (selective laser melting) method. This type of scaffold insert made from pure Ti powder, was placed into mould cavity directly before pouring by grey cast iron. In result of used method was obtained grey cast iron casting with surface layer reinforced by titanium carbides. In range of studies were carried out metallographic researches using light microscope and scanning electron microscope, microhardness measurements and abrasive wear resistance. On the basis of obtaining results was stated that there is a possibility of reinforcing surface layer of the grey cast iron casting by using 3D printing scaffold insert in the method of mould cavity preparation. Moreover there was a local increase in hardness and abrasive wear resistance in spite of the precipitation of titanium carbides in surface layer of grey cast iron. While the usable properties of composite surface layer obtained in result of use of the method presented in the paper, strongly depend of dimensions of scaffold insert, mainly parameters Re and Ri.

Opis:
The work presents the results of a study on cavitation erosion (CE) resistance of two NiCrSiB self-fluxing powders deposited by oxy-acetylene powder welding on cast iron substrate grade EN-GJL-200. The mean hardness of deposits A-NiCrSiB, C-NiCrSiB is equal to 908 HV, 399 HV and exceeds those of EN-GJL-200 and X5CrNi18-10 reference specimens 197 HV and 209 HV, respectively. To study CE, the vibratory apparatus has been used and tests were conducted according to the ASTM G32 standard. Cavitation eroded surfaces were examined using a profilometer, optical and scanning electron microscopy. The research indicated that the CE resistance, expressed by the cumulative mass loss decreased in the following order C-NiCrSiB > A-NiCrSiB > X5CrNi18-10 > EN-GJL-200. Therefore, hardfacings were characterised by lower cumulative mass loss, in turn, higher CE resistance than the reference sample and therefore they may be applied as layers to increase resistance to cavitation of cast iron machine components. Results indicate that in the case of multiphase materials, hardness cannot be the main indicator for CE damage prediction while it strongly depends on the initial material microstructure. To qualitatively estimate the cavitation erosion damage (CEd) of NiCrSiB self-fluxing alloys at a specific test time, the following factors should be considered: material microstructure, physical and mechanical properties as well as surface morphology and material loss both estimated at specific exposure time. A general formula for the CEd prediction of NiCrSiB deposits was proposed.
