Abstract
The article deals with results of investigation of properties of nickel and cobalt alloys, deposited on copper or its alloys. Investigations of corrosion resistance of these alloys at different types of corrosion (solid, contact, crevice, cavitation-erosion fracture), as well as their antifriction properties and adhesion strength showed that the most acceptable as to the combination of properties are alloys NKh16SR2 and KKh30N6VSR. The technology of automatic plasma-powder surfacing of these alloys on aluminum bronze Br.AZhNMts9-4-4-1 was developed providing a quality joining of the deposited metal and the base one. The technology and equipment found application in surfacing of parts of ship pipeline fittings. 4 Ref., 1 Table, 6 Figures.
