Abstract

The effect of the initial structure of the fillers on the structure formation of the dissolution-and-diffusion type interfaces in macroheterogeneous composite coatings with a metal binder has been investigated. It has been shown that by combining phases in the filler structure, which differ in resistance to molten binder during infiltration, it is possible to attain an increased resistance of composite coatings to dry friction, abrasive, gas abrasive, and corrosion wear. The compositions of composite coatings to strengthen the surface of the parts of machine-building industry have been recommended.
