“…This result agrees with some works in the literature, e.g. [1,3,9]. According with several authors [9,10,12,16,17], that as the sliding distance increases, the wear mode changes from mechanically dominated wear to tribochemically dominated wear and the surface smoothening is a result of the tribochemical wear which has a fundamental role to obtained the steady-state friction coefficient of mean value in the range of 0.001.…”

“…There is a tendency of increasing transition time with increasing initial surface roughness of the discs. This result agrees with the literature [3,17]. One accepted explanation is that smoother surfaces need less time to adjust themselves for an adequate lubrication condition to occur the regime of ULFC.…”
