Abstract
Existing first-principle-based models have primarily addressed single-asperity interactions; however, the behavior of multiple contacting asperities remains inadequately understood. This study investigates the adhesive wear behavior and material transfer mechanisms of a multi-asperity interface in dry friction conditions, focusing on an alumina/polytetrafluoroethylene (PTFE) composite. By applying Rabinowicz's critical size criterion and Monte Carlo simulations, we analyzed the statistical wear characteristics of asperities. Our findings indicate that the simulated wear coefficient approximates 10−4, aligning well with experimental values. Additionally, the asperity size, material property, and their distribution strongly affect polymer wear behavior and material flow during the steady-state wear period. This research offers novel insights into the complex interactions at dry friction interfaces, paving the way for optimized material design and performance.
期刊介绍：
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
