Improving wear resistance of magnesium by droplet spraying of Al-Si alloyXIE Kun(谢鲲), CAO Mei-qing(曹梅青), XIA Peng-cheng(夏鹏成), YUE Li-jie(岳丽杰)(School of Materials Scinence and Engineering, Shandong University of Science and Technology,Qingdao 266590, China)Abstract:In order to improve the surface hardness and wear resistance of magnesium, Al-13%Si (mass fraction) alloy coating was deposited......
J. Cent. South Univ. (2016) 23: 2771-2776 DOI: 10.1007/s11771-016-3339-y Wear resistance of TC4 by deformation accelerated plasma nitriding at 400 °C ZHU Xiao-shuo(朱小硕)1, FU Yu-dong(傅宇东)1, 2, LI Zi... nitriding process for TC4 (Ti6Al4V) has been developed and the effect on wear resistance has been investigated. Through the process of solid solution strengthening-cold deformation-nitriding at 400 °C......
Wear behavior of Al-Si alloy matrix composites reinforced by γ-Al2O3 decomposed from AACH FU Gao-feng(付高峰)1, ZHANG Jing-xin(张景新)2, LIU Ji(刘 吉)1, WANG Zhao-fei(王肇飞)1 1. School of Materials.... It is found that the γ-Al2O3 particles distribute more uniformly in the matrix by adding AACH than by adding γ-Al2O3 directly. The wear tests show that the volume loss of the unreinforced Al-Si alloy......
Influence of processing parameters on microstructure and wear resistance of Ti+TiC laser clad layer on titanium alloy WU Wan-liang(武万良), SUN Jian-feng(孙俭峰), DONG Sheng-min(董胜敏), LIU Rong-xiang(刘荣祥.... Microstructure, microhardness and wear resistance of the clad layer were evaluated. The results show that the laser parameter has considerable influence on microstructure and wear resistance of laser clad......
