the grinding abrasion and the electrochemical corrosion with medium water. The wear phenomenon is the complex results from the wear and corrosion. 3.2 Evaluation of corrosion rate To well... approximating that of the stainless steel. Thus it can be used as wear-resistant materials with good corrosion resistance. 4 CONCLUSIONS 1) Under the same load and grinding abrasion, the wear rate......
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......
layer. With the optimized technical parameters, a clad layer with good surface quality and uniform microstructure was obtained. The microhardness of the clad layer HV0.2 is 1 080, and the wear rate... with the untreated titanium alloy, the coatings have a wear rate an order of magnitude less. The results of laser cladding of titanium alloys with NiTiSi mixed powders demonstrate that Ti5Si3, NiTi2, NiTi......

Wear behaviors and lubrication medium of TiC/Al2O3 ceramic wire drawing dies YANG Xue-feng(杨学锋)1, DENG Jian-xin(邓建新) 2, WANG Hui(王 慧)1, ZE Xiang-bo(昃向博)1 1. Department of Mechanical... on the drawing force was investigated. The wear mechanisms of the ceramic drawing dies were investigated. Worn bore surfaces of the ceramic drawing dies were examined by scanning electron microscopy......
after 6 h nitriding with different deformation degrees 3.4.2 Wear The wear rate of specimens with different deformation degrees after nitriding for 6 and 7 h are illustrated in Fig. 10. As can be seen, no matter the nitriding time is 6 or 7 h, the wear rate of 30% deformed specimen is lower than that of the undeformed specimen. Compared with the wear rate of undeformed specimen, the wear rate......
