Description
Summary:Peculiarities of variation in hardness and structure of the matrix alloy, Stellite, depending on a composition of the ceramic-metal system were found out in studying the effects of hardening of the base layer of cermet coatings. A new type of structure of matrix alloy, which was called “meshwork,” were discovered and examined as well as a new type of inclusions: plasma conglomerates, in which a fragmentary structure refinement was found. Under the conditions of the plasma stream new composite coatings of multilayer structure characterized by improved performance properties were produced.
