HOMOGENIZATION TREATMENT OF Mg-Al-Zn (MM) MAGNESIUM ALLOY INGOTS K.Yu1,W.X.Li1 (1.College of Materials Science and Engineering, Central South University, Changsha 410083, China) Abstract:The Mg-Al-Zn series AZ31 and AZ314+MM alloys are homogenized at 673, 723 and753K respectively. The hardness of alloy ingots at different heat-treated states ismeasured and the microstructures are observed......
Laser Cladding of an Al-11.7Wt% Si Alloy on ZM5 Magnesium Alloy to Enhance the Corrosion Resistance WANG Mao-cai1,WANG Dong-sheng1,CHEN Chang-jun1 (1.State Key Labatory for Corrosion and Protection, Institute of Metal Research, Chinese Academy of Sciences, Shenyang, P.R. China 110016) 摘要:Magnesium alloy is an important engineering materials, but the wider application is restricted by poor......
Pre-electroless nickel plating It is difficult to obtain the adherent deposit on magnesium alloys with high content of aluminum such as AZ91D Mg alloy. However, the process that following pre... containing alkaline electrolyte were used to produce a chemical conversion coating and a Zn-Ni alloy on the coated sample, respectively. The cross-sectional microstructure of the AZ91 Mg alloy......
, Mn2O3, Mn3O4) and other species such as Mg3PO4, MgO, Al2O3, C, Na3PO4, and K3PO4. The metal elements of Mg, Al, Zn should come from the substrate of magnesium alloy. The substrate oxides, such as MgO... difference between Zn (-0.76 V) and Cu (+0.34 V). Copper plating as cathode of the corrosion cell is protected, but the uncovered zone on magnesium alloy substrate as anode is fiercely dissolved so......
Fretting wear behavior of AZ91D magnesium alloy CHEN An-hua(陈安华)1, HUANG Wei-jiu(黄伟九)2, LI Zhao-feng(李兆峰)2 1. School of Mechanical Engineering, Hunan University of Science and Technology... behaviour of the AZ91D magnesium alloy was investigated. The influence of the number of cycles, normal load (contact pressure) and the amplitude of slip on the fretting behavior of the material were......
