  • Archard’s wear equation has been widely used in industry for preliminary selection of materials mainly based on hardness. According to Archard’s equation, the material wear rate is linearly proportional to the normal force. However, the wear rate or material volume loss per unit sliding distance is usually not linear with the normal force. The non-linear relationship should result from variations in the resistance of a material to wear due to changes in the mechanical behavior of materials such as strain-hardening capability. In this study, we performed sliding wear tests to determine and analyze the material loss – normal load curves of three alloys, Al5182 (FCC), AZ 31 alloy (HCP) and the high strength low alloy (HSLA) steel (BCC). The volume loss ~ normal load curves did not appear as straight lines. An attempt was made to understand this phenomenon and extract additional information from the non-linear volume loss ~ normal load relationship.
