Deposition of a TiC/Ti Cermet Coating on VT3-1 Titanium Alloy

TiC/Ti cermet coatings were produced on VT3-1 titanium alloy by electrical discharge treatment in a mixture of titanium granules with the addition of 2, 6, and 10 vol % titanium carbide powder. The titanium carbide concentration in the coating increased with increasing TiC powder content in the anode mixture. At the same time, the coating microhardness increased from 6.82 to 8.69 GPa, and the friction coefficient decreased from 0.65 to 0.42. The use of TiC/Ti coatings makes it possible to increase the wear resistance of the VT3-1 titanium alloy surface by up to 17 times.
