The Buckingham’s dimensional analysis is applied to dry sliding contact to determine a relationship between wear and entropy flow. The obtained nondimensional groups are correlated using experimental results pertaining to wear tests of a sliding contact in a disk-on-disk configuration for two sets of contacting materials, namely, bronze SAE 40 on steel 4140 and cartridge brass on steel 4140. The results of analysis are employed to calculate the Archard’s wear coefficient K. The obtained wear coefficient is compared with the available data in literature.
