,loading to a strain failure of the MWCNTs rather than an adhesive failure between the MWCNTs and the matrix.关键词:......
erosion and adhesive wear, while for CNTs-Cu composites are adhesive wear. Key words: Cu matrix composite; tribological behaviors; electric current; wear mechanisms 1 Introduction As a sort of high.... The worn micrographs of CNTs-Cu composite with 5% CNTs are shown in Figs. 7(c) and (d). It is noted that abrasive and adhesive wear with deep grooves happened on the surface of the CNTs-Cu composite......

adsorbed in the basement of titanium alloy were observed. Based on the surface characteristics of materials, the contact angle and adhesive work of erythrocyte with different HCT on the surface... performance is improved; with the increase of roughness of titanium surface, the contact angle and adhesive work increase; with the increase of hydrophilicity of titanium, the lubrication performance......
adhesive performance was obtained on the surface which was coated with 0.5% SDBS and 0.5% fluorocarbon composite reagents. The experiment results indicated that each reagent had a certain optimum adhesive range to the particle. The composite reagents with different proportion of single reagents exhibited some particular physical and chemical properties, which could effectively change the adhesive......
and fractured surface were observed and analyzed by scanning electronic microscopy(SEM).It was identified that the semi-metallic friction materials doped with cerous nitrate acted abrasive wear and adhesive wear at the low temperature,and abrasive wear,adhesive wear and fatigue wear of materials appeared at the high temperature.The fracture of materials might be the result of matrix cracking interacting......
oxidation and adhesive wear at the same time,with the load at 350-450 N,adhesive wear with irregular debris and peeling wear were predominant.关键词:......
that the worn surface of metal-PTFE multilayer composites was characterized by adhesive wear, abrasive wear and fatigue wear. The CNTs greatly increased the adhesion strength of PTFE in the metal... self-lubricating film, in which the oscillating wear mechanism of the composites was changed to a slightly adhesive wear. Therefore, the CNTs significantly decreased the weight loss and obviously......
