成完整的摩擦膜,而采用另两种技术制备的C/C复合材料均形成了较完整,致密的摩擦膜. 关键词:C/C复合坯体；碳化硅；氮化硼；摩擦磨损 中图分类号:TB 332 文献标识码:A C/C composites modified by B, Si and their friction and wear... by CVD changes in 0.20?0.36, while the composites modified by c-BN using impregnation and in-situ reaction hold the lowest friction coefficient, which is 0.10?0.20. The wear surfaces of the RMI-modified......
properties of MoSi2 against Al2O3 were investigated by using an XP-5 type High Temperature Friction and Wear Tester. Micrographs and phases of the worn surface of MoSi2 were observed by SEM with EDS and X-ray... composites (such as adding WSi2, Mo5Si3, La2O3, B4C and Ag/ZrO2) against carbon steel. All above researches are limited to the range of room temperature. The high temperature friction and wear......
Received 28 November 2005; accepted 1 April 2006 Abstract: The influence of graphite particle content on the friction and wear characteristics of AZ91 magnesium alloy matrix composite was studied... substantially with the increase of the graphite content from 5% to 20%, and both wear mass loss and coefficient of friction are decreased to low level. Different wear mechanisms operate at different......

Friction and Wear Behavior of AlTiN-Coated Carbide Balls Against SKD11 Hardened Steel at Elevated TemperaturesRui Wang1,2,Hai-Juan Mei1,Ren-Suo Li2,Quan Zhang1,Teng-Fei Zhang1,Qi-Min Wang11. School...">In this study, AlTiN coatings were deposited on YT14 cemented carbide balls by arc ion plating technique. The friction and wear behavior of the AlTiN-coated balls against SKD11 hardened steel......
on the interface between the Ni-Pb monotectic alloy and steel ball restricts metal-metal contact, and hence the resistance to wear and friction is improved. 3.2 Surface morphology and wear mechanism...) The wear rate of samples undercooled by 80K and 310K is obviously smaller than that of the others, which is attributed to more efficient transfer of Pb from the bulk material to the friction surface. 2......
Influence of loading and rotation speed on Friction and Wear properties of CuAlBi Alloy刘荣昌,董丽涛,李兴元,陈秀宏摘 要:The variation of the friction coefficient of the CuAlBi alloy at different connecting loading and friction speed were investigated by using MMU-5G sliding friction-wear tester, besides, the wear mass loss of the CuAlBi alloy was measured......
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......
