THE EFFECT OF PARTICLE SHAPE ON THE ABRASIVENESS OF LAMELLAR SOLIDS

Abstract

The abrasiveness of samples of graphite of controlled shape has been shown to be related to the aspect ratio of the crystallites. A decreasing aspect ratio results in increasing abrasiveness. Whilst the same kind of relationship is valid for MoS2, its more complex surface chemistry does not yet permit the direct calculation of crystal aspect ratios. The effect of particle shape on the abrasiveness of graphite and MoS2 is interpreted mainly in terms of the probability of crystals presenting edge faces to the surfaces in the sliding environment.
