Abstract

Coatings with an ultradispersed structure and a nanostructure, which have a high wear resistance, corrosion resistance, and a satisfactory ductility, are fabricated by electron-beam vacuum-free deposition of a powder mixture of chromium carbide, chromium, and titanium carbide using a relativistic electron accelerator. The increase in the wear resistance and the ductility is shown to be associated with the modifying influence of titanium carbide, which manifests itself in sharp structure refinement the presence of numerous nucleation centers in it in the form of disperse TiC precipitates.
