Abstract
In wear research, as in other areas of scientific endeavor, discoveries of empirical correlations between particular properties of combinations of properties continue to be reported. Usually they extend only to a limited group of more-or-less similar materials. Ultimately, of course, all such correlations must be explicable, in principle if not in practice, in terms of a proper quantum mechanical treatment of the relationship between each of the properties involved and interatomic cohesion. In the absence of such understanding, the value of such correlations depends primarily on how widely they extend. The present paper reports a Bureau of Mines investigation into the problem of relating abrasive wear to other mechanical and/or physical properties. It begins by demonstrating that the correlation between abrasive wear and enthalpy of vaporization reported for pure metals cannot always be extended to binary alloys in which the two components exhibit complete mutual solid solubility. It then proposes a plausible, if simplistic, dislocation-based model of abrasive wear and demonstrates that this model does not lead to any simple relationship between abrasive wear and enthalpy of vaporization, even when interatomic cohesion is characterized by very simple models.
