Abstract

Impulse coaxial magneto-plasma accelerator supersonic stream of electrodigit plasma. With a barrel length of up to 250 mm, the discharge is accelerated by a current 100 + 150 κA to a velocity of 3+5 km/s at atmospheric pressure. Up to 10 g of metal is taken out of a barrel. Researches on a raster electronic microscope have shown: uniformity of a covering, absence of pores and a dense interface from a surface of a substrate. The formation of a boundary layer of mutual mixture of materials of a covering and substrate by thickness 50 + 150 micron is established. It causes an extremely high adhesion of a covering from stainless steel on duralumin. A great number of jet inclusions of dense substance extending in thickness of a substrate starting ∼ from 150 microns up to 500 microns have been found out. This layer has high nanohardness. Increase of wear resistance of a surface for more than on two order. The processing of a surface of the details made of aluminium alloys by a high-velocity stream of electrodigit plasma of structure of stainless steel provides an essential increase of mechanical properties. The received covering can carry out anticorrosive functions and functions of thermal barrier.
