and Ti2O3 obviously improve the wear resistance of TiAl alloy. The wear rate is -3.27×10-7 g/(N?m). Key words: TiAl alloy; micro-arc oxidation coating; additive; corrosion resistance; wear resistance 1...]. Under arc discharge at high voltage on the anodic surface, a dense ceramic coating grows in situ on the surface of TiAl alloys by plasma chemistry and electrochemistry reaction. Wear resistance, high......
Wear resistance of ceramic coating on AZ91 magnesium alloy by micro-arc oxidation ZHAO Hui(赵 晖)1, 2, LIU Zheng(刘 正)1, CHEN Li-jia(陈立佳)1, CHEN Ji(陈 吉) 3, HAN Zhong(韩 忠)3 1. College of Materials... the substrate. Dry sliding wear tests for the MAO coatings and AZ91 alloy were also carried out using an oscillating friction and wear tester in a ball-on-disc contact configuration. The wear resistance......
%, the grain size becomes small. Moreover, with increasing the graphite content, the microhardness of the composites decreases but the wear resistance increases. The graphite which works as lubricant during... is still with abrasive wear and oxidation wear, the wear mechanism of other composites changes to delamination wear.
