abstract="It is known that surface roughness affects friction. However, it is not clear which surface characteristics are better correlated with friction. An extensive search for a relationship between surface roughness parameters and friction was completed in this study. Surface roughness on unglazed quarry tiles was systematically altered by sand blasting. A commercially available pin-on-disk tester was used to measure dynamic friction under broad testing conditions at the interface. A commercially available profilometer was used to measure the surface roughness of the tiles. The results indicated that, among the surface parameters evaluated in this study, Rpm and a had the highest correlation with friction. Rpm is the average of the maximum height above the mean line in each cut-off length and represents the averaged void volume among asperities on the surface.a is the arithmetical average of surface slope and is related to the rate of asperity deformation during a sliding contact. The averaged surface parameters generated from eight surface measurements from an area of interest were sufficient to give a fairly good indication of surface friction.<p />",
