Dry Friction and Wear Characteristics of Rare-Earth/MoSi2 Composite 龙春光1,张厚安1,陈平1,刘心宇3 (1.Institute of Material Surface Engineering, Xiangtan Polytechnic University, Xiangtan 411201, China;2.School of Materials Science and Engineering, Center South University, Changsha 410083, China;3.Guilin Institute of Electric Technology, Guilin 541004, China) Abstract:The dry friction and wear......
Microstructure, Mechanical Properties and Wear Behaviourof Deep-Cryogenic-Treated HSS and J.Vi1,V.Leskov2,M.Kalin3 (1.z)intin(z;2.s)ek(s;3.z) 摘要:In this paper we compare the wear behaviour... and the Rockwell-C hardness. Each of the eight specimens was therefore characterised by these microstructures and resulting material properties.The wear study was performed using a reciprocating sliding device......
Tribological property and wear mechanism of undercooled Ni-Pb monotectic alloys XIE Hui(谢 辉)1, YANG Gen-cang(杨根仓)1, HAO Wei-xin(郝维新)1, LA Pei-qing(喇培清)2, LIU Wei-min(刘维民)2, XU Li-jun(许丽君)1... and melt undercooling on wear rate of the sample were investigated. The worn surface of Ni-31.44%Pb was examined using scanning electron microscope (SEM) and X-ray photoelectron spectroscope (XPS......
Effect of graphite content on wear property of graphite/Al2O3/Mg-9Al-1Zn-0.8Ce composites ZHANG Mei-juan(张美娟)1, YANG Xiao-hong(杨晓红)1, LIU Yong-bing(刘勇兵)1, CAO Zhan-yi(曹占义)1, CHENG Li-ren(程丽任)1... phases combined closely with the matrix and no agglomeration was observed. The microstructure, hardness and wear property of the composites with the graphite content of 5%, 10%, 15% and 20% were......
Wear characteristics and prediction of wheel profiles in high-speed trainsHAN Peng(韩鹏)1, ZHANG Wei-hua(张卫华)1, LI Yan(李艳)2(1. State key Laboratory of Traction Power (Southwest Jiaotong University), Chengdu 610031, China;2. China Railway Eryuan Engineering Group Co.
