Effect Of Applied Load On Wear Behavior Of Some Copper Alloys

Abstract

This research devoted to studying the properties of sliding wear ofthree groups of copper alloys chosen to this study. They are Brass (70/30),Silicon bronze and Silicon-Brass. These three groups have been examinedby using (pin on Disc) apparatus under different wear conditions includingapplied loads and disc hardness is constant (35HRC). This study wasconcluded that the wear rate was increased as the applied load and the wearbehavior was changed from mild wear into transition wear as the appliedload is increased. This research concludes that the alloy of Silicon-brass wasthe best alloy due to high wear resistance in comparison with the otheralloys.
