| Abstract Scope |
Wear is an inherently complex phenomenon that significantly impacts industrial performance, necessitating a fundamental understanding of its mechanisms to improve wear resistance. In particular, strain-path changes during abrasive wear—commonly observed in industrial settings—remain poorly understood due to their complexity. As a result, conflicting findings in the literature have yet to be fully explained. This study addresses this gap by investigating the strain-path dependence of wear through a micro-mechanical approach. Using in-situ micro-scratch testing with a pico-indenter under both continuous and reciprocating modes, coupled with SEM and AFM-based microstructural analysis, we systematically compare wear behavior under varying strain paths. Our findings clarify the conditions under which each mode leads to higher wear rates and provide insight into previous research. These results also contribute to a deeper understanding of wear mechanisms and offer guidance for enhancing wear resistance in industrial applications. |
