results of heat treatment processes.However, these results were insufficient to predict crack generation clearly because the mechanism relates not only to stress distributions in the parts but also... were simulated for considering a cause of the crack generation. Lastly a tentative plan was made for the future research. 关键词:Quench Cracking; Heat Treatment Simulation; [全文内容正在添加中] ......
EFFECT OF VACUUM HEAT TREATMENT ON OXIDATION BEHAVIOR OF SPUTTERED NiCrA1Y COATING M.H.Li1,X.F.Sun1,Z.Q.Hu1,Z.Y.Zhang1,W.Y.Hu2,H.R.Guan1 (1.Institute of Metal Research, The Chinese Academy..., is subjected to vac-uum heat treatment in order to remove internal stress before ceramic top coat is de-posited. The effect of vacuum heat treatment on the oxidation behavior of the sputteredNiCrAlY coating......

-deposition temperature and heat treatment were also investigated. By galvanostatic cell cycling the film anodes can deliver a steady specific capacity. The morphological changes cause the differences in capacity retention. After farther heat treatment, the film anodes present a better cycle performance, with a specific capacity of 314 mA?h/g after 100 cycles. This high capacity retention can be due to its......
