A theory of friction and wear during the abrasion of ...

Expressions are derived for the ploughing- (μ p), adhesion- (μ a) and total (μ) friction coefficients of spheres, cones and triangular- and square pyramids (with axis normal to the metal surface) ploughing along the surface of a metal. The effects of clogging of bonded abrasives such as emery paper by worn-off metal, and of pick-up of abrasive particles by the metal surface, are also considered quantitatively.

Surface Re-orientation, Friction and Wear, in the ...

Surface structure, friction and wear are investigated and correlated in the case of abrasion of graphite by emery papers of particle diameter D=5 to 150 microns. For graphite and also for metals, the coefficient of friction μ of specimens approximately 1 cm long or more is low on the fine grades of emery, but rises rapidly with increasing D and then is practically constant at D>50 microns.
