Abrasive wear mechanisms and the grit size effect
TLDR
In this article, it is shown that the grit size effect is a consequence of the transition from a cutting mechanism to a sliding wear mechanism, and that the wear coefficient is less than that predicted by a cutting model owing to the plastic deformation of the surface being worn.About:

The genesis of friction
Nam P. Suh,H.-C. Sin +1 more
TL;DR: In this paper, the genesis of friction is explained in terms of a new theory, which postulates that the frictional force (and thus the friction coefficient μ) is affected by the sliding distance and the environment because of the changing contributions of three components of friction, i.e., deformation of surface asperities, plowing by wear particles and hard as perities, and adhesion of the flat portions of the sliding surface.

On the size effect in abrasive and erosive wear
Ambrish Misra,Iain Finnie +1 more
TL;DR: In this paper, the authors present results for erosion and two-and three-body abrasion using a range of particle sizes, and draw on the grinding and metal-cutting literature, concluding that shallow surface layers exhibit a higher flow stress than that of the bulk material when they are abraded or eroded.
Journal ArticleDOI
Analytical models of scratch hardness
TL;DR: The ability of one material to abrade or scratch another has a long history as the basis of a scale of hardness and is clearly related to the now more common measure of hardness as the resistance of a material to indentation as discussed by the authors.

The delamination theory of wear
TL;DR: A new theory for wear of metals is considered in this article, which is based on the behavior of dislocations at the surface, sub-surface crack and void formation, and subsequent joining of cracks by shear deformation of the surface.

A study of abrasive wear under three-body conditions
TL;DR: In this article, a simple quantitative expression for abrasive wear rate is developed, and the abrasive data of a number of earlier investigators is analyzed in terms of this expression. But the results of this analysis are limited, since the average loose abrasive grain spends 90% of its time rolling and only 10% of the time abrading the sliding surfaces between which it is situated.
