2011 Abstract: The wear rate between the rotors of a hypotrochoidal gear pump is characterized. Using the knowledge of shape design on the rotors, the contact stresses without hydrodynamic effect... as an optimization technique for minimizing the wear rate proportional factor (WRPF). The result shows that the wear rate or the WRPF can be reduced considerably, e.g. approximately 12.8%, throughout......
) and oxide ceramics (Al2O3 and PS-ZrO2). They have found that the wear resistance of MoSi2 is improved greatly after adding Nb, which wear rate is near Al2O3 and PS-ZrO2. After analyzing abrasion property of SiC/MoSi2 composite, PAN et al[5] have found the wear rate of MoSi2 is decreased by about 90% with the addition of SiC. The authors[6-13] have ever studied the tribological property of MoSi2 and its......
, worn surfaces and wear debris of the alloys were analyzed using scanning electron microscope (SEM). The results show that the wear rate of the alloys increases almost linearly with increasing applied load and decreases with increasing sliding speed. The wear rate of the as-cast alloy is higher than that of the cast+T6 alloy. The amount of Mg12Y1Zn1 phase, surface oxidation and retained wear debris......

. It is found that the 11% SiC MMC wear rate is higher on SiC abrasives compared with the 50% SiC MMC wear rate due to wear of the aluminum matrix. This trend is reversed on diamond abrasives due... condition; T6 condition; wear rate; hardness; porosity 1 Introduction Metal matrix composites (MMCs) are natural materials of choice for wear sensitive applications. Attractiveness for making MMC......

Sliding wear behaviors of electrodeposited Ni composite coatings containing micrometer and nanometer Cr particles ZHAO Guo-gang(赵国刚), ZHOU Yue-bo(周月波), ZHANG Hai-jun(张海军) College... nm. The friction and the wear performance of the co-deposited Ni-Cr composite coatings were comparatively evaluated by sliding against Si3N4 ceramic balls under non-lubricated conditions. It is found......
Microstructures and wear properties of graphite and Al2O3 reinforced AZ91D-Cex composites ZHANG Mei-juan(张美娟)1, 2, CAO Zhan-yi(曹占义)1, YANG Xiao-hong(杨晓红)1, LIU Yong-bing(刘勇兵)1 1. Key Laboratory... dispersed uniformly and no agglomeration and casting defect were observed. The microstructures and wear properties of the composites with different Ce contents of 0, 0.4%, 0.8% and 1.0%, respectively......
