MANUFACTURING METHOD OF FUNCTIONAL SURFACE Russian patent published in 2009 - IPC C23C24/04 C23C28/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to method of manufacturing of functional surface and can be used in mechanical engineering, for instance, for forming of reflecting and other metal-containing coatings. It is implemented gas-dynamic sputtering by powder material with rains size 0.01-50 mcm from chosen materials and material in the form of spheroidized particles with size 70-300 mcm made of steel and other solid magnetic medium It is used feedback system between coating thickness and density of evaporated material flow and/or velocity of travel sputtering spot of evaporation relative to detail surface. Evaporated powder material is tagged rate providing connection to the surface and to particles of treated material - rate, providing impact moulding of evaporated material. It is implemented surface finish by programmable mechanical operation till nominal dimensions of its profile and roughness. Process is implemented with simultaneous pumping out, catching and separation of materials particles. Temperature of surface and gas powder flow of evaporated material is lower the temperature of recrystallisation soft component of evaporated powder material.

EFFECT: receiving of reflecting surface with defined parameters of curvature and roughness.
