with the largest graphite particle size has the best wear resistance. The wear mechanism of all the composites at low load is abrasive wear and oxidation wear; at high load, except the composites with the particle size of 240 μm whose wear mechanism is still abrasive wear and oxidation wear, the wear mechanism of others changes to dellamination wear. Key words: magnesium matrix composite; particle size......
to identical test for comparison. The wear mechanism has been examined. 2 Experimental AZ91 alloy having the chemical composition given in Table 1 was chosen as the base matrix alloy in the present... induces abrasive wear, manifesting itself by distinct scratches and grooves on the worn surface (Fig.6(b)). Consequently, it can be concluded that the main wear mechanism in this process is abrasive wear......
