Structure and wear regularities of coatings from composite metal-ceramic materials of the SiC-Al2O3-Ni-Al system

The structure of coatings from composite material containing the SiC-Al2O3 wear-resistant component and a Ni-Al metallic binder has been investigated. The coatings have been produced by the high-velocity air fuel deposition (HVAF) onto medium-carbon steel. The tribotechnical characteristics of these coatings have been studied in dry friction in air and special features and regularities of their wear mechanisms have been defined.
