A theory on galling wear has been proposed by R. Holm, that is, the amount of wear is proportional to the normal pressure and sliding distance, while it is inversely proportional to the hardness of the softer of the two rubbing materials. The theory has been improved and demonstrated experimentally by several investigators. However, actual wear characteristics are apparently more complicated. The authors have attempted to find a simple theory, which reduces the complication of actual test results by the aid of dimensional considerations, and have seen that the rate of wear par unit normal pressure and sliding distance is a function of dimensionless numbers, containing PV and V, where P and V denotes normal pressure and sliding velocity respectively, and have shown that above result is formally identical with Holm's theory.
