High-Temperature Oxidation of WC-20%TiC-10%Co Carbides

Abstract:

The oxidation characteristics of WC-20%TiC-10%Co sintered carbides were studied by oxidizing at 700, 800 and 900 °C for 3 h in air. The samples oxidized fast with large weight gains, displaying quite poor oxidation resistance. The formed oxide scales that consisted primarily of CoWO₄, WO₃, and TiO₂ were porous, and prone to cracking.
