Present paper focuses on the dry sliding wear behavior of rheocast Mg–Sn based alloys under ambient temperature. The alloys were studied through pin-on-disc wear experiments under four different loading conditions, namely, 9.8, 19.6, 29.4 and 39.2 N. Present investigations highlight the influence of load on the cumulative wear loss, volumetric wear loss, dry sliding wear rate and co-efficient of friction of the different alloys under study. The volumetric wear was found to be increased with increasing applied load. Different wear micro-mechanisms were observed under electron micro-scope. The wear occurs mainly by ploughing mechanism and by delamination also. During wear, extensive plastic deformation and work hardening took place for all the alloys mainly at the higher loads. Micro-structural analysis has been performed for all the alloys at different loading conditions.
