STUDY ON CO-ELECTRODEPOSITION OF Bi-Fe ALLOY FILMS IN ORGANIC BATH G.K.Liu1,Y.X.Tong1,G.R.Li1 (1.School of Chemistry and Chemical Engineering, Zhongshan University, Guangzhou 510275, China) Abstract:The cyclic voltametry and potentiostatic electrolysis was used to investigate the preparation of Bi-Fe alloy films in LiClO4-DMSO (dimethylsulfoxide) system. The effects of several factors......
In-plane anisotropy of 1545 aluminum alloy sheet PENG Yong-yi(彭勇宜)1, 2, YIN Zhi-min(尹志民)2,YANG Jin(杨 进)2, DU Yu-xuan(杜予晅)2 (1. School of Physics Science and Technology,Central South... in the rolling plane of 1545 aluminum alloy sheet at different orientations with respect to the rolling direction were studied by means of tensile test, X-ray diffractometer(XRD), optical microscope......
on ME20 mainly consists of MgF2, MgO, C and a small amount of CeF4. The good oxidation resistances of ZK60 and ME20 alloy melts may be caused by their major alloying elements Zr and Ce, respectively. Key words: ZK60 alloy; ME20 alloy; magnesium alloy melt; Mg melt; 1,1,1,2-tetrafluoroethane; alloying element; oxidation 1 Introduction Molten magnesium has an extremely high affinity for oxygen and high......
