Comparison of Wear Behaviour of Mg, Mg-4Zn, Mg-4Zn-3MnO2 & Mg-4Zn-3MnCl2 Systems
Study involves the comparison between wear properties of commercially pure Mg, Mg-4Zn, Mg-4Zn- 3MnO2 and Mg-4Zn-3MnCl2 by addition of Zn and Mn (by changing their sources). The wear behaviour of all systems investigated under applied loads of 5, 10, 15, 20, 25 and 30 N at the room temperature. The wear tests carried out by pin-on-disk type wear testing machine at sliding speed of 0.25 m/s for a total sliding distance of around 452 meter. The result shows that the wear property of pure magnesium improved by addition of 4.0% zinc but by addition of manganese in improvement of wear properties is not noticeable. At lower load condition (5N & 10N) the highest wear resistance obtained in Mg-4Zn-3MnCl2 system. At higher load (20N, 25N & 30N) wear resistance remain almost equal in all systems (Mg-4Zn, Mg-4Zn-3MnO2 & Mg-4Zn-3MnCl2).
