AbstractTwo composite coatings are manufactured by reactive magnetron sputtering on superalloys. The effect of titanium on oxidation resistance and microstructural change of composite coatings were studied. Titanium in superalloys reacted with [N] ions in composite coating due to interdiffusion. The position of reaction zone was determined by the relative content of [N] ions and metallic aluminum in coating. Doping of titanium in alumina lead to a decrease of charged oxygen vacancies but Ti-A1(center dot) forms in this process. The transportation of Ti-A1(center dot) in oxide scale resulted in the formation of TiO2 and a higher oxidation rate of coating.
