and a large number of large sized wear debris. The wear mechanism mainly is adhesive wear and there is a small amount of oxidation wear as well. At oxidation wear stage, although the friction coefficient...:A Effect of temperature on friction and wear characteristics of as-cast SiCp/A356 composite JIN Yun-xue1, WANG Xiao-ya1, TONG Qiang-qiang1, CHEN Hong-mei1, Jung-Moo LEE2 (1.

strain limit εp of composite are 520 MPa and 11.2%, respectively. The fretting wear mechanism of MMCs is mainly performed at the oxidative wear mode with lower load/friction frequency and the predominant oxidation wear together with slight adhesive wear and abrasive wear multiple mode with higher load/ friction frequency. Moreover, the infiltration bonding and continuous three-dimensional......
, cohesive failure, rather than conventional wear [1]. Cohesive failure results from stresses within the layers and at the surface, while adhesive failure occurs due to interface stresses. When designing..., the medium elastic module value is more suitable for stress distribution in crown-luting cement-substrate interfaces. Key words: finite element modeling; stress analysis; adhesive and luting cement......
coefficient and wear loss are decreased obviously after burnishing process. Moreover, the wear mechanisms of untreated specimens are mainly adhesive wear and fatigue wear, whereas the treated specimens...; 文章编号:1672-7207(2017)04-0896-07 Effect of burnishing on fretting wear behaviors of carbon steel QU Shengguan1, HE Ruiliang1, WANG Guanghong1, FU Zhiqiang2, LI Xiaoqiang1......

The results indicated that differences in the alloy compositions significantly influenced the initial deposition process and the adhesive strength, corrosion... activation rather than on the precipitates. Owing to differences in the initial deposition process, the coating on ZK60 alloy had higher adhesive strength and better corrosion resistance than that on ME20......
