| Summary: | Title from the title-page. 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) кА 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) μm 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 μm up to 500 μm 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. Режим доступа: из корпоративной сети ТПУ Text files |
