Abstract

In this paper, we obtain cermet coatings with a thickness of 19 to 22 μm by the method of electrospark treatment of titanium alloy Ti6Al4V in a mixture of titanium granules with hafnium carbide powder. An increase in the volume fraction of hafnium carbide powder in the mixture of granules from 2.4 to 6.7 vol % led to an increase in the concentration of the hafnium carbide phase HfC in the coatings. The coating structure is represented by a metallic Ti–Hf–C binder with large inclusions of hafnium carbide. The average microhardness of Ti–HfC coatings was in the range of 7.1–8.3 GPa, which is 2–2.5 times higher than that of the Ti6Al4V alloy. Wear tests in dry sliding mode showed that Ti–HfC coatings had a wear rate in the range from 3.18 × 10–6 to 1.5 × 10–5 mm3/(N m), which is 25 to 250 times higher than that of Ti6Al4V titanium alloy.
