static oxidation of the material under normal atmosphere follows the parabolic law. Oxide increases with increasing temperature and prolonging time. It has good oxidation resistance. The product...Oxidation of Al2O3-30%TiCN-0.2%Y2O3 Composite Yan Changhao1,Li Xikun2,Xiu Zhimeng3,SUN Xudong3,QIU Guanming1,Dai Shaojun1 (1.Nanjing University of Technoloy, Nanjing 210009, China;2.Shenyang......
show that with the addition of Cr content from 0 to 8%, the oxidation resistance decreases, especially at 3%, which is mainly attributed to the doping effect of Cr3+. TiAl-Cr(mole fraction of Cr?15%-20%) has good oxidation resistance, and the protective alumina layer is preferentially formed on the surface of TiAl alloy, which is due to an increase of mole ratio of Al to Ti in TiAl-Cr alloys. Key......
