Microstructure and properties of oxalate conversion coating on AZ91D magnesium alloy JIANG Yong-feng(蒋永锋), ZHOU Hai-tao(周海涛), ZENG Su-min(曾苏民) School of Materials Science and Engineering, Central...; Abstract: The oxalate coating formed on AZ91D magnesium alloy by chemical conversion treatment methods in oxalate salt......
. Various surface treatment, chemical conversion, anode oxidation, painting and electroplating for magnesium alloys were investigated extensively, but a great improvement of corrosion resistance and wear resistance of magnesium alloys could not be gained by chemical conversion, anode oxidation and painting[6]. The electroplating is mainly conducted with cyanide and CrO3 or chromate solutions[7], hence......
Anodization of AZ91 magnesium alloy in alkaline solution containing silicate and corrosion properties of anodized films LI Ling-ling(李玲玲)1, CHENG Ying-liang(程英亮)1, WANG Hui-min(王慧敏)1, ZHANG Zhao(张...; Abstract: The anodization of AZ91 magnesium alloy in an alkaline electrolyte of 100 g/L NaOH+20 g/L Na2B4O7?10H2O+50 g/L C6H5Na3O7?2H2O+60 g/L Na2SiO3?9H2O was studied. The corrosion resistance......
electrode potential of magnesium is -2.37 V, but in 3% sodium chloride the electrode potential is -1.63 V(vs SCE). Therefore magnesium is often used as a sacrificial anode. On the other hand, magnesium... were investigated by TONG et al [11]. The results show that the magnesium alloys act as anode and that their corrosion rates increase when they are coupled with the above mentioned four metals......
