Abstract
Effect of Ti addition on oxidation behavior of Ni-Cr-W alloys was systematically investigated by isothermal oxidation in air. The oxidation rate is accelerated by Ti addition, due to that Cr2O3 vacancy density is increased by Ti4+ occupies Cr3+ position, which promotes the formation of Cr2O3 scales. Ti addition induced the formation of TiO2 but inhibited the formation of Ni oxide. Ti segregated on the external Cr2O3 scales after oxidation for a period time. Besides, internal oxidation and nitridation were found in both alloys containing Ti. The depth of internal oxidation and nitridation increases with the increase of Ti content.
