One of the most advanced and effective methods to increase machines and mechanisms component life is the application of hardening coatings on their working surfaces. The coatings from self-fluxing alloys on nickel base, which are applied by means of plasma spraying, have acquired wide application in different engineering fields. Increase of properties and cohesive resistance of plasma coatings from self-fluxing alloys on nickel base is possible by means of surface coating fusion at the definite temperature.
