Abstract
It has been empirically understood that one can diminish wear by reducing adhesion between sliding surfaces. A clear contribution of interfacial adhesion into the process of surface material removal, however, remains elusive as most wear observations are obtained from post-factum analyses of worn surfaces. Investigating the complete life of an adhesive wear particle, from the formation and growth to detachment, using novel atomistic simulations, this study reveals that reducing interfacial adhesion diminishes the adhesive wear in three disparate ways: i) reducing the probability of surface material removal, ii) increasing the required energy to remove a unit volume of surface material, and iii) alleviating the growth of formed material fragments.
