Meanwhile, with the meshing parameter of the tooth surface and grinding wheel, the material removed simultaneously can be estimated, which is useful to improve the grinding force model and predict the surface roughness of spiral bevel gears.

The Effect of Grain Size and Cl-Concentration on the Passive Behavior of Cu in Borate Buffer Solution Qijun Zhong1, Libin Yu1, Yi Xiao1, Yi Wang1,a, Qiongyu Zhou1,b, Qingdong Zhong1,c* 1Key Laboratory of Modern Metallurgy and Material Processing, Shanghai University, Shanghai 200072,China akasuo.9@163.com , bzhouqiongyu1986@sina.com,cqdzhong@shu.edu.cn Keywords: Grain size;Cl- Concentration;passive films; Mott-Schottky analysis Abstract:Effect of grain size and Cl- concentration on corrosion behavior of Cu was investigated by using a series of electrochemical analysis in borate buffer solution (pH=8.40).The results indicated that in all cases, the Mott-Schottky plots of the passive films on the surface of Cu were linear with negative slop, and showed behavior of the p-type semiconductor.With the decrease of the grain size and the increase of anode passivation potential, the acceptor density (NA) of the passivation film on the surface of Cu was reducing.
