Oxidation resistance of TiC-SKD11 composite has been improved through SiC/TiB2 based hybrid coating by a simple air spray process and subsequent transition to dense and stable phases in oxidation environment. As a result of the oxidation test at 700 degrees C for up to 50 h, the coated TiC-SKD11 composite exhibited excellent oxidation resistance characteristics compared with the uncoated TiC-SKD11 composite, and also compared to SUS431 and 17-4PH. The formation of a thermally stable, volume-expanded SiO2 and TiO2 coating layer with the aid of B2O3 by phase transition of TiB2/SiC based hybrid coating under oxidation atmosphere is the origin of the improved anti-oxidation ability of the TiC-SKD11 composite.
