The Effect of Alloying, Processing and Heat Treatment on the Wear Resistance of Al-Cu-Mg-Ag Alloys

In this study, eight aluminum-based alloys with two levels of weight percentages of copper, magnesium, and silver were cast and hot rolled. The alloys were processed at two conditions; hot rolled solely or hot rolled and aged to peak condition (T6). Statistically designed experiments were carried out to investigate the wear resistance of the aluminum-based alloys. The study investigated the following process variables: the effect of the level of alloying, the processing condition, the level of applied load, and the test duration on the wear performance and weight loss as a response variable. Analysis of variance (ANOVA) was carried out to define the significant factors. The means effect and interactions plots were extracted, and the regression model was developed and experimentally validated. The weight percentages of Cu and Ag, applied load, and test duration were found to be significant. The wear resistance improved with increasing percentages of Cu, Mg and Ag and the peak aging. The regression model represented the experimental results properly.& COPY; 2023 Jordan Journal of Mechanical and Industrial Engineering. All rights reserved
