This paper examines the oxidation behavior of tungsten carbide with a 6% cobalt binder, after exposure to air furnace temperatures in the range 500 °C-1,000 °C. Oxidation of carbide and binder takes place, forming an intimate mixture of the two compounds. A surprisingly uniform composition is produced from the oxide surface to the oxide/cermet interface. At 700 °C, there is no detectable diffusion gradient for oxygen. These phenomena are explored in terms of oxidation rate and exposure temperature.
