Abstract:
Protective coatings for machine parts can be economically viable if the wear is localized or if the coating material has different properties than the substrate. Technological surface layers (TSLs) are applied to objects before use, while functional surface layers (FSLs) are applied during maintenance. [..]

Abstract:
This article deals with the evaluation of the microstructure and tribological and mechanical properties of hardmetal coatings based on WC and CrC, which were applied to the base material S235JR by the HVOF thermal spraying technology. Experiments such as microhardness HV0.3, superficial hardness HR15N, adhesion determination, abrasive wear and reciprocating sliding wear test were performed to compare the properties of the coatings and see how they differ depending on the selected additive material.

Abstract:
It has been observed that the products obtained by means of 3D printing technology, even in the case of consideration of optimal parameters of printing technology recommended by the manufacturers of metal powders laser sintering systems, are characterized by certain structural discontinuities (pores and unmelted powder) in surface layer. Therefore, surface modification via shot peening is considered suitable for additive manufacturing of parts made of 17-4PH stainless steel. [..]

Abstract:
Complex concentrated alloy (CCA) with a nominal composition Al0.4CoCr1.3FeNi1.3(Si, Ti, C, B)0.4 was prepared at two different solidification conditions. Centrifugal casting (CC) of the CCA was applied due to the turbulent filling of a graphite mould at non-steady solidification conditions and directional solidification (DS) was performed at steady-state solidification conditions.

Abstract:
Welding of components processed by additive manufacturing (AM) to conventionally produced components become important for industrial applications. Among AM production methods, selective laser melting method provides number of advantages such as use of various type of materials, increased functionality, relatively low cost and the production of smooth surface components ready to use.Within the scope of this study, preliminary research studies were carried out to demonstrate the feasibility of similar and dissimilar friction stir welded AlSi10Mg plates produced by selective laser melting.

Abstract:
Through the rising amount of hydrogen in natural gases provided by the suppliers technical questions about the process control based on the off-gas composition as well as about the supply of the necessary process heat come up. But also the hydrogen solubility plays a significant role in many processes in which solid or liquid metals like copper are produced. [..]

Abstract:
Currently, an avalanche of technology development can be observed, which results in an increase in the production and sale of electrical and electronic devices. The lifetime of electronic components, which at the end of the 20th century was 4 to 6 years, was shortened to 2 years in the first decade of the 21st century, and even to 9 months in the case of mobile phones.

Abstract:
Because of a limited source of germanium and its high demand caused by growing technology industry, secondary sources become attractive and suited alternatives. In the present paper copper slag containing germanium was used as source and aluminothermic reduction was adopted as mode of reduction. [..]
