High temperature oxidation of double carbide based hard alloys

Abstract

Dependences of the oxidation kinetics in air of titanium and vanadium carbide based hard alloys with a nickel-chromium binder and the structure, phase and chemical composition of the formed scale in the temperature range 800–1100 ̊С were found. The regularities of the oxidation process were determined by the weight method, the main kinetic characteristics were calculated.
