Abstract
Nowadayspulsed plasma processing systems are rapidly developing which is expected to achieve more effective results. This paper shows the results of studies ofplasma flows effects generated in VAA-1 vacuum-arc accelerator. Material is treateddue to thermo-physical processes associated with emission of cathode material. The paper presents the results of experiments on coatings obtaining from copper using pulsed vacuum-arc method on a substrate of structural materials such as carbon steel, tool steel, and aluminum.
