ИССЛЕДОВАНИЕ КОМПОЗИЦИОННЫХ ЭЛЕКТРОИСКРОВЫХ ПОКРЫТИЙ НА ОСНОВЕ КАРБИДА ТИТАНА С ИСПОЛЬЗОВАНИЕМ САМОРАСПРОСТРАНЯЮЩЕГОСЯ ВЫСОКОТЕМПЕРАТУРНОГО СИНТЕЗА

Rezumat

The composite coatings obtained by the method of electrospark doping and the self-propagating high-temperature synthesis have been examined. It is revealed that the generated composite coatings consist of the titanium carbides which are uniformly distributed in the metal matrix. The grains of titanium carbide are of the size of 0,1–4,0 microns. Large titanium carbide grains in the coatings consist of disperse carbides of the size less than 1 micron. The investigation of the structure of the composite coatings in the friction tracks after the performed tests has shown that the formed coatings have high wearing capacity.
