Electrolyte Optimization of Microarc Oxidation of Magnesium Alloy WANG Ji-hui1,FANG Da-ran1,YANG Jing1 (1.College of Materials Science and Engineering, Tianjin University, Tianjin, 300072, P. R.. China) 摘要:Magnesium alloy AZ91D was processed respectively in one, two, three and four-component electrolytes by using AC microarc oxidation technique. The corrosion resistance of AZ9 1D alloy......
content of 1%-4% on microstructures and elevated temperature mechanical properties of AZ81 magnesium alloy were investigated. The results show that, proper content of rare earth elements makes the microstructures of AZ81 magnesium alloy refine obviously and the quantity of β-Mg17Al12 phases reduce, and Al2Y and Al2Nd form. After solid solution treatment, with increasing content of rare earth......
