Opis:
In this work, the change of the structure and microhardness of Ti6Al4V titanium alloy after remelting and remelting with SiC alloing by electric arc welding (GTAW method) was studied. The current intensity equal 100 A and fixed scan speed rate equal 0,2 m/min has been used to remelting surface of the alloy. Change of structure were investigated by optical and scanning electron microscopy. Microhardness test showed, that the remelting of the surface does not change the hardness of the alloy. Treated by GTAW SiC alloying leads to the formation of hard (570 HV0,1) surface layer with a thickness of 2 mm. The resulting surface layer is characterized by diverse morphology alloyed zone. The fracture of alloy after conventional heat treatment, similarly to fracture after remelting with GTAW is characterized by extremely fine dimples of plastic deformation. In the alloyed specimens the intergranular and crystalline fracture was identified.

Opis:
Purpose: The application of a common magnetron discharge to the growth of carbon nanostructures is studied. The simplicity of the proposed technique can be beneficial for the development of new plasma reactors for large-scale production of carbon nanostructures. Design/methodology/approach: Graphite cathode was treated by carbon-containing powder accelerated by use of nozzle, and then aged in hydrogen. Superposition of glow and arc discharges was obtained, when putting the cathode under the negative biasing with respect to the walls of a vacuum chamber. The pulsed discharge was preserved through the whole time of treatment. This process was explained in terms of interaction of glow discharge plasma with a surface of the cathode made of non-melting material. Findings: The plasma treatment resulted in generation of the diverse nanostructures confirmed by SEM and TEM images. Spruce-like nanostructures and nanofibers are observed near the cathode edge where the plasma was less dense; a grass-like structure was grown in the area of “race-track”; net-like nanostructures are found among the nanofibers. These findings allow concluding about the possible implementation of the proposed method in industry. Research limitations/implications: The main limitation is conditioned by an explosive nature of nanostructure generation in arcs; thus, more elaborate design of the setup should be developed in order to collect the nanospecies in the following study. Practical implications: High-productivity plasma process of nanosynthesis was confirmed in this research. It can be used for possible manufacturing of field emitters, gas sensors, and supercapacitors. Originality/value: Synthesis of carbon nanostructures is conducted by use of a simple and well-known technique of magnetron sputtering deposition where a preliminary surface treatment is added to expand the production yield and diversity of the obtained nanostructures.

Opis:
The article presents research on the development of technology and mechanical properties of a 16Mo3 steel tube overlaid with Inconel 625 nickel superalloy using robotized Plasma Powder Transferred Arc Welding (PPTAW) process. Based on the results of non-destructive, metallographic and microscopic observations, chemical composition, thickness and hardness measurements of overlays optimal technological parameters for working in elevated temperature environment were selected. The performed test has shown the correct structure of the overlay weld without welding imperfections. The examined padding weld was characterized by a dendritic structure with primary crystals growing in the direction of heat removal. It has been stated that in the range of heat input to base material 277÷514 J/mm, the iron content in the surface zone of 1,5 mm padding weld ranges from 4 to 5,5%.
W artykule przedstawiono wyniki badań dotyczących opracowania technologii napawania i właściwości mechanicznych rury ze stali kotłowej gatunku 16Mo3 pokrytej zewnętrzną warstwą plateru z nadstopu niklu Inconel 625 nanoszonego w procesie zrobotyzowanego napawania plazmowego proszkowego (PPTAW). W oparciu o wyniki badań nieniszczących, metalograficznych makro- imikroskopowych, składu chemicznego oraz pomiarów grubości i twardości warstwy plateru, wytypowano optymalne parametry technologiczne wykonywania tego typu zabezpieczeń na elementach rurowych konstrukcji energetycznych pracujących w podwyższonej temperaturze. Przeprowadzone badania wykazały prawidłową budowę warstwy plateru bez niezgodności spawalniczych. Badana warstwa charakteryzowała się budową dendrytyczną o kryształach pierwotnych narastających w kierunku odprowadzania ciepła. Wykazano, że przy ilości ciepła wprowadzonego do materiału rodzimego z zakresu 277÷514 J/mm, zawartość żelaza w strefie przypowierzchniowej plateru o grubości ok. 1,5 mm mieściła się w przedziale od 4 do 5,5%.

The aim of the work was to review selected methods of plasma nitriding, which according to the authors might he used in the thermo-chemical treatment of aircraft parts. The introduction explains the nitriding process and presents the requirements on the thermo-chemical treatment of aircraft parts. Three methods of plasma nitriding have been described: Direct Current Plasma Nitriding (DCPN), Active Screen Plasma Nitriding (ASPN) and Low Pressure Nitriding in AEGD (Arc Enhanced Glow Discharge) plasma. While describing DCPN plasma nitriding method, authors drew attention to known problems, which occur in this process such as edge effect or hollow cathode effect. The Keller's model, the Marchand's model and the Walkowicz's model of nitriding process, which can be found in the literature, were also presented in this work. Another purpose of this work was to present hypotheses about the transportation of nitrogen during Active Screen Plasma Nitriding process and to show that in this nitriding method, defects typical for Direct Current Plasma Nitriding do not occur. While describing Low Pressure Nitriding in AEGD plasma, authors also presented the model of nitriding mechanism in this process, which shows four nitrogen diffusion paths (physisorption, chemisorption, adsorption ofNj, ion implantation). Examples of layers obtained by applying described nitriding methods were presented. The measurement ofnitrided layers confirmed that it is possible to obtain a layer without E film on the surface.

Opis:
A state-of-the-art fabrication of Y2O3 transparent ceramic by arc plasma synthesis using commercial micron-size powders is reported. The morphological observations of the surface by scanning electron microscope shows that a dense microstructure can be obtained. Arc melted samples are made of a white core and transparent layer. X-ray diffraction studies and also Raman spectroscopy confirm that only one phase occurred in the core and in the transparent layer, and that the physicochemical difference exists. The obtained Y2O3 shell ceramics have pores but also relative low absorbance in the VIS-NIR region after double side polishing. The optical band gap and the refractive index are reported. It is concluded that arc plasma melting allows obtaining quickly (10 minutes) dense and highly transparent polycrystalline samples, especially in the VIS-IR spectral region.

Opis:
This article discusses plasma cutting technology and its influences on the quality of the resulting cut. Plasma or a plasma arch consists of positive and negatively charged particles, excited and neutral atoms and molecules. As it contains free particles, it is electrically conductive and thus subject to the effects of the electrical and magnetic field. The basis of CNC machine design is described in the article, which has at least 3 axes (x, y, z), but there are also more technologically demanding applications, such as pipe cutting, profile and cutting using chamfer to prepare surfaces for welding, where these multi-axis devices are frequently used. The principle of plasma cutting and the plasma cutting phase is described in this article. The materials that can be divided by a plasma arc are described in detail, including graphs displaying the dependence of sheet thickness on the cutting speed. The article describes and lists the gases that are used in plasma-arc cutting, such as oxygen, argon, hydrogen and nitrogen. Important components of plasma cutting technology are the parameters that can be adjusted and set before the cutting so that the cut is of good quality. The most comprehensive chapter deals with the influences that affect plasma cutting quality. Cutting quality can be influenced by a number of factors. Everything starts with the proper choice of a CNC machine and a plasma source. The quality also depends on the expertise and experience of the machine operator and the setting of the plasma cutting parameters. This issue of influences on the plasma cutting quality is based on long-term experience in the field of the thermal cutting process.

Opis:
The carbon steel for ąuenching and tempering has been cut with two different techniques, plasma arc and laser. The influence of these two unconventional methods of cutting on the changes of microstructure and properties has been studied in this paper. The structure changes after cutting were investigated by means of both light and scanning electron microscopy, additionally microhardness in the heat affected zone was measured. The performed investigations show that both methods of cutting have a strong influence on the structure and properties of investigated steels. Characteristic structure of cut area was a bainitic structure. The amount of bainite structure decreased with increased distance from the edge of the cutting sample. The plasma arc cutting influences the structure changes morę than laser beam. The bainitic structure after this method of cutting was observed to a depth of near 130 micrometers (laser), whereas after plasma arc - average 400 micrometers. Measured microhardness at the edge after cutting by both methods was about 28OHvO.l what makes up 130% increase comparing to materiał beyond the heat affected zone.

W artykule przedstawiono porównawcze wyniki badania mikrostruktury i mikrotwardości w strefie wpływu ciepła po cięciu stali tymi dwiema metodami. Cechą charakterystyczną było wystąpienie struktury bainitycznej w strefie wpływu cięcia. W przypadku cięcia laserem struktura bainitu obserwowana była do głębokości około 130 (Jm, z kolei po cięciu łukiem plazmowym strefa wpływu sięgała aż do głębokości 400 nm. Zmierzona mikrotwardość przy krawędzi po cięciu zarówno łukiem plazmowym, jak i laserem wynosiła około 280 Hv0,l, co w porównaniu z materiałem poza strefą wpływu stanowi wzrost o ponad 130%.

A bottom up approach for the preparation of Nano Aluminium Powder (NAP) using a Transferred Arc Thermal Plasma Reactor (TAPR) is described. The aluminium block is subjected to evaporation by the application of a thermal plasma. The aluminium vapour produced is rapidly quenched to room temperature resulting in crystallization of the aluminium vapour in nano-particulate form. Various process parameters, such as the plasma torch power, reactor pressure and plasma gas composition were optimized. This paper also describes the characterization of NAP by analytical methods, for the estimation of the Active Aluminium Content (AAC), Total Aluminium Content (TAC), XRD, bulk density, BET surface area, HR-TEM etc. The results are compared with those for samples prepared in other thermal plasma reactors, such as the DC Arc Plasma Reactor (DCAPR) and the RF Induction Thermal Plasma Reactor (RFITPR), and for commercially available NAP samples (ALEX, prepared by the EEW technique).
