; 文献标识码: A Influence of load, time, speed on sliding tribology behavior of C/C... wear tester, the sliding tribology behavior of three kinds of C/C composites with different matrix carbon were investigated with 40Cr steel coated by Cr or W18Cr4V steel as couple. The result shows......
of Mechanical and Electrical Engineering, Central South University, Changsha 410083, China;)Abstract:The calculation method of relative sliding speed, contact stress and friction heat flow during the meshing... and the effect of pressure angle were studied. The distribution curves of these parameters were analyzed. The results show that when the pressure angle increases, the relative sliding speed and tooth......
, of 0.2–0.4 μm. Three normal loads of 100, 200, and 300 N were applied to the ring at a steady linear sliding speed of 2 m/s, which was affected by circular rotation at 800 r/min, under dry...-PPS composites with the Al2O3 nanoparticle content. The wear tests were carried out under dry sliding conditions at a normal load of 200 N, sliding speed of 2 m/s, and sliding distance of 7200 m......
TRIBOLOGICAL AND HIGH SPEED TURNING PERFORMANCE IN Ti1-xAlxN COATINGS PREPARED BY CLOSE-FIELD UNBALANCED MAGNETRON SPUTTERING Y.G. Shen1,Z.F. Zhou1,T.H. Wong1,K.Y. Li1,M. Escursell1,P.W. Shum1... by sliding against steel and WC-6wt%Co balls, while the turning performance was evaluated by a conventional turning machine at high cutting speeds without using coolants. In the tribological tests......
microstructure is obtained. Grain boundary sliding is the main mechanism during the isothermal forging process with a low speed, and the diffusion creep is the main factor leading to the grain boundary sliding. Therefore, based on the vacancy diffusion theory, the plastic deformation constitutive equation of aviation forging under extremely low speed isothermal forging process is established......
Influence of graphite content on sliding wear characteristics of CNTs-Ag-G electrical contact materials WANG Juan(王 娟), FENG Yi(凤 仪), LI Shu (李 庶), LIN Shen(林 森) Department of Materials Science...; Abstract: CNTs-Ag-G electrical contact composite material was prepared by means of powder metallurgical method. The influence of the graphite content on sliding......

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......
