FIELD: machine building.
SUBSTANCE: items out of steel and alloy are subjected to cathode sputtering and vacuum heating in plasma of glow discharge of increased density; also, plasma consists of mixture containing nitrogen and inert gases; mixture is formed between item and shield. Notably, non-uniform plasma of glow discharge is formed by means of the shield with cells, thus a differential structure in material is created by forming heterogeneous structures. Additionally, the transition section between sections with different structures has a micro-non-uniform structure with gradual transition from one kind into another.
EFFECT: increased contact service life and wear resistance of strengthened layer, expanded functionality.
