Abstract
In an earlier paper it was suggested that the wear resistance of a metal would be proportional to H s/(1−ƒ p) where H s is the hardness of the wear surface and 1− ƒ p is the fraction of a wear groove removed from the wear surface. However, the expression derived for 1−ƒ p could not explain the abrasive wear resistance of very ductile materials. In this work it is proposed that the abrasive wear resistance will scale as H s(1− ƒ) eff and an expression for (1− ƒ) eff has been derived. An initial assessment using data from the literature for values of H s and to evaluate (1− f) eff suggests the proposed scaling is reasonable. However, geometric considerations suggest the approach underestimates (1− f) eff for metals of low work-hardening capacity.
