Obtaining and Investigating Wear Resistance of a Composite Material Based on Titanium Carbosilicide

摘要

A composite material (CM) based on titanium carbosilicide with a titanium carbide content of 50% possessing a microcrystalline structure is obtained by mechanosynthesis in a planetary mill with subsequent hot pressing. The highly nonequilibrium structure of the powder material, which forms due to the high-energy treatment, makes it possible to obtain material with a relative density of 96% at a hot-pressing temperature of 1400°C and a pressure of 20 MPa. Comparative tests of the CM and silicon carbide for wear resistance under different conditions are carried out. The CM based on titanium carbosilicide showed less wear of the counterbody and a lower friction coefficient in all cases. However, in tests using an abrasive medium, wear of the composite material itself is observed.
