WebApr 12, 2024 · When the removal rates were compared on the basis of the coefficient of friction regardless of fiber type, the samples with a coefficient of friction between 0.165 and 0.18 (Pk, Ck, and Wk) showed low removal rates of 30% or less, whereas those that had a low coefficient of friction (between 0.10 and 0.165; Pw and Cw) had high removal rates … WebThe coefficient of friction for PA/steel contacts is reported to be generally below 0.8, but also extreme values of 2.0 were observed by Watanabe et al. [10]. Also, a discrepancy in the friction behaviour was observed; sometimes the coefficient of friction increased with increasing load [8,12,13], but sometimes it decreased with increasing load [7,14].
