Traditionally, the wear of materials has been characterized by weight loss and wear rate. However, studies have found that wear coefficient is more suitable. The reason being that it takes the wear rate, the applied load, and the hardness of the wear pin into account. Although, measurement variations by an order of 10-1 have been observed, the variations can be minimized if suitable precautions are taken. WebThe wear rate was calculated using the following formula: Wk=Wv/M.S mm3/Nm (1) Where Wk is the wear rate, Wv the worn volume, M the applied load and S is the sliding distance. Cite. 1 ...
