Influence of plasma stream parameters in pulsed plasma gun on modification processes in exposed structural materials

摘要

This paper is focused on investigation of helium, nitrogen and krypton plasma streams generated by pulsed plasmaudgun (PPA). The main objection of this study is adjustment of plasma treatment regimes for different materials thatudallows achieving optimal thickness of modified layer with simultaneously minimal value of surface roughness. Featuresudof materials alloying from gas and metallic plasma as a result of the plasma ions mixing with the steel substrate in liquidudphase are discussed also.
