Abstract
The theoretical conditions and principles for the formation of coatings from metal powders stratified in chemical and phase composition using a combination of methods are developed. Wear resistant inclusions of defined size and concentration are placed in a diffusionally alloyed or eutectically melted matrix. Composite coatings for operation under stationary friction conditions with a required gradient of structure and properties are formed by the thermochemical treatment (diffusional alloying or eutectic melting) of matrix-filler electrolytic deposits. The optimal classes of graded coatings are defined on the basis of modeling the stress state of the coatings.
