Effect of Ca and Y additions on oxidation behavior of AZ91 alloy at elevated temperatures CHENG Su-ling(程素玲), YANG Gen-cang(杨根仓), FAN Jian-feng(樊建锋), LI You-jie(李佑杰), ZHOU Yao-he(周尧和... magnesium alloy, the effect of alloying elements, Ca and Y, on the oxidation behavior of AZ91 magnesium alloy at elevated temperatures was investigated. The ignition-proof performance, oxide products......
friction coefficient of 0.14 and longer wear life of 2450 m of overcoat were observed for the polished micro-arc oxidation coating of 180μm thick at a sliding speed 2. 50 m/s and load 1500 N... in the porous holes of the overcoat and provided the lubrication of micro reservoir during friction, and the compact and relatively hard interlayer of oxidation coating is able to support heavy load......
Friction and Wear Characteristics of Mg-Al Alloy Containing Rare Earths 杨晓红1,刘勇兵1,祁庆琚1 (1.College of Materials Science and Engineering, Jilin University, Changchun 130025, China) Abstract:The influence of rare earth on the friction and wear characteristics of magnesium alloy AZ91 and AM60 were studied. The results show that the wear resistance properties of rare earth magnesium alloys......
lubricating films on micro-arc oxidation(MAO) coating was introduced to provide self-lubricating and wear-resistant multilayer coatings for aluminum alloys. The friction and wear behavior of various... and a reciprocating friction and wear tester, respectively. The burnished and bonded solid lubricating films on the polished micro-arc oxidation coatings are superior to the as-deposited ones in terms......
