Abstract

In our study, the effect of disk rotational speed on abrasive wear coefficients of solution treated Al-Mg-Si and Al-Zn alloys was evaluated. The abrasion tests were done at rotational speeds of 50-200RPM. A constant load of 10 N was applied. The grit size of abrasive sheet (emery paper) was 100┬Ám.The tests were conducted on 60mm and 120mm Track diameters. The volume loss and dimensional wear coefficients were calculated and plotted with respect to rotational speeds. In the present set of experiments, as the rotational speed increases, the volume loss increased for both the alloys, wear coefficients slightly increased for Al-Mg-Si alloy and wear coefficients slightly decreased for Al-Zn alloy.
