Abstract
Any method to be used to investigate the performance of bearing metals should reproduce wear under service conditions and in addition it should show variation in wear with unit pressure. Various methods have been proposed in the past, one of which involves an accelerated test using an abrasive between two surfaces rubbing across each other, and another utilizes two tangent cylinders rotating relatively to each other and making contact along their common element. The first method does not reproduce wear under service conditions, while the second results in a constant contact area so that in order to test a metal completely many runs must be made at various unit pressures. The new method described in this paper reproduces wear under service conditions and gives variation in rate of wear with unit pressure.
