This work studies the effect of reinforcement weight percentage (Wt.%SiC) on wear and mechanical behaviour of the aluminium 7075 composites produced by the powder metallurgy technique. The three different reinforcements weight percentage used in this study are to 5,10 and 15. The hardness and toughness values reveals that with an increment in weight percentage of reinforcement, the mechanical properties decreases because of the development of large and more number of pores and agglomerations. The composites wear behaviour is examined by the wear testing equipment. The selected tribological parameters for the study are reinforcement weight percentage, applied load and sliding distance at three levels. The Design of Experiments, Box-Behnken method is used to design the number of experiments. ANOVA is used to find the effect of input parameters on output responses. The response surface methodology confirms that sliding distance and reinforcement weight percentage are two parameters which mostly affects wear loss.

这项工作研究了粉末冶金技术生产的铝7075复合材料的重量百分比（SiC重量百分比）对磨损和机械性能的影响。本研究中使用的三种不同的增强材料重量百分比分别为5、10和15。硬度和韧性值表明，随着增强材料重量百分比的增加，机械性能会下降，这是因为孔的数量增加和数量增加所致。集聚。复合材料的磨损行为由磨损测试设备检查。研究中选择的摩擦学参数是三个级别的配筋重量百分比，施加的载荷和滑动距离。实验设计Box-Behnken方法用于设计实验数量。ANOVA用于查找输入参数对输出响应的影响。响应面法确定滑动距离和增强重量百分比是两个主要影响磨损损失的参数。
