Abstract
The article presents the results of a study of the microstructure of composite cermet coatings formed by carbovibro-arc hardening using multicomponent pastes containing tungsten carbide as a hardening component. It is shown that the composite cermet coatings obtained using this paste have a two-layer structure. The X-ray phase analysis and scanning electron microscopy reveals the strengthening phases characteristic of the main and transition zones of the coatings. The distribution of chemical elements in the cross section of the coatings confirmed their high adhesion strength.
