A Review on Fretting Wear in Aluminium Composites and Its Mitigation through Surface Engineering

This article reviewed the fretting wear of aluminium matrix composites and its mitigation through the application of surface engineering techniques. The concept of fretting damage, which could be in the form of fretting wear, fretting fatigue and fretting corrosion, was elucidated. This was followed by an expository study on the mechanisms of fretting wear, stages of fretting wear and the four basic operation modes of fretting wear. Experimental and numerical methods for the study of fretting wear were outlined. The numerical methods for the study of fretting wear reviewed in this article were the Archard model and the energy model. A review of surface engineering techniques for the mitigation of fretting wear was carried out, and scholarly articles on the mitigation of fretting wear through surface coatings were presented. A recap of materials for tribological applications was also highlighted. This review provides useful insights into the mitigation of fretting wear through surface engineering.
