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......
on the erosive wear behavior of ductile material rotating in slurry tank. Erosion wear behavior of commercial grade aluminum has been studied by rotating the specimens in a slurry tank containing 40... Erosive wear occurs when the impingement of hard particles flows in a fluid stream at high velocity. The kinetic energy of the moving particles is mainly responsible for the loss of material......
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......
