rate and wear resistance of extruded Mg-9Sn and Mg-9Sn-3Yb alloys were measured within a load range of 20–240 N and 20–380 N at a sliding velocity of 0.785 m/s, respectively. The wear tracks, worn surface and wear edge were observed using a scanning electron microscope and an energy dispersive X-ray spectrometer. The results indicated that wear rate, coefficient of friction and wear resistance......
