and the testing conditions. The wear mechanism diagram of MZA is constructed, it contains two typical regions. It suggests that the wear mechanisms of MZA in each of the region change from one to another depending on the wear conditions. In the mild wear region, the wear rate of MZA is 10-6mm3/m, and the wear mechanism of MZA is plastic deformation accompanied by a little micro-cracking......

Effect of Pearlite Interlamellar Spacing on Predominant Abrasive Wear Mechanism of Fully Pearlitic Steel M. Monirvaghefi1,M. Salehi1,J. Ahmadi2,B.Niroumand1 (1.Isfahan University of Technology, Department of materials engineering, Isfahan, Iran;2.Merat poolad engineering company, Isfahan, Iran) 摘要:The aim of this investigation was the determination of the predominant wear mechanism on three......
adhesion, plastic forming to fatigue fracture in turn. Key words: MoSi2; tribological property; wear mechanism wear-resistance under 50 N. Fig.2 Variation of friction coefficient with load Fig.3 Variation of wear rate with time Fig.4 Variation of wear rate with load 3.2 Wear mechanism......
resistance and wear mechanism of the hardfacing layer were studied.The experimental results indicate that the hardfacing technology has much more advantages and cheaper than that of traditional... layers were carried out by using two different electrodes. The wear resistance of new electrode hardfacing layer is higher than that of normal hardfacing electrode D322. The wear mechanism of hardfacing......
with the increase of normal load in the mixed and gross slip regime, but the normal load has no obvious effect on the wear volume in the partial slip regime. The predominant fretting wear mechanism of magnesium alloy in the slip regime is the oxidation wear, delaminated wear and abrasive wear. Key words: AZ91D magnesium alloy; fretting; friction coefficient; wear mechanism; wear behavior 1......
