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......
Microstructure and wear resistance of Ti-3Zr-2Sn-3Mo-15Nb (TLM) alloy YU Zhen-tao(于振涛)1, ZHENG Yu-feng(郑玉峰)2, NIU Jin-long(牛金龙)1, HUANGFU Qiang(皇甫强)1, ZHANG Ya-feng(张亚峰)1, YU Sen(余森)1 1... microscopy. The wear resistance of TLM alloy was tested by sliding wear in comparison with as-annealed Ti-6Al-4V and as-aged Ti-13Nb-13Zr. The results show that the specimen cooled from α+β dual phase......
normal loads of 50, 80 and 110 N. Based on the analysis of the frictional kinetics of the torsional fretting wear and combined with the micro-examinations, the damage characteristics of alloys TC4 and TA2...伤加剧,扭动微动摩擦磨损机制主要为磨粒磨损,氧化磨损和剥落. 关键词:钛；钛合金；摩擦磨损；微动磨损；扭动微动；磨损机制 中图分类号:TH117 文献标志码:A Torsional fretting friction and wear behaviors of titanium and its alloy HE Li-ping, LIN Xiu......

may get oxidized because of high frictional heat and form a layer (mechanically mixed layer), which acts as a lubricating film, thus enhancing the wear resistance. Figure 4(i) shows the existence... be noted that, material removal took place by delamination and plastic deformation (abrasive wear). Increase in load leads to the generation of high frictional heat between the pin sliding face and disc......
