“…Plastic deformation of diamond at room temperature under similar loading conditions to those used in the present work has been reported and studied by several investigators (Bowden, Brookes and Hanwell 1964, Brookes 1970, Brookes, O'Neill and Redfern 1971. Conclusive evidence has been given by Humble and Hannink (1978) who used transmission electron microscopy (TEM) and observed the generation and movement of dislocations under Knoop indentation marks on diamond surfaces.…”

“…In 1964, Steijn (238) and Bowden et al (239) first observed crystallographic orientation dependence on the coefficient of friction of single-crystalline, ordered solids, including rock salts, diamond, and face-centered-cubic and body-centered-cubic metals. Both Steijn and Bowden et al performed experiments on the same {001} family of planes of the rock salt structure; Figure 14 shows the result of the anisotropy in friction for Steijn's NaCl experiment (Figure 14a) and for Bowden et al's MgO experiment (Figure 14b).…”

From the context of a contemporary understanding of the phenomenological origins of friction and wear of materials, we review insightful contributions from recent experimental investigations of three classes of materials that exhibit uniquely contrasting tribological behaviors: metals, polymers, and ionic solids. We focus on the past decade of research by the community to better understand the correlations between environment parameters, materials properties, and tribological behavior in systems of increasingly greater complexity utilizing novel synthesis and in situ experimental techniques. In addition to such review, and a half-century after seminal publications on the subject, we present recently acquired evidence linking anisotropy in friction response with anisotropy in wear behavior of crystalline ionic solids as a function of crystallographic orientation. Although the tribological behaviors of metals, polymers, and ionic solids differ widely, it is increasingly more evident that the mechanistic origins (such as fatigue, corrosion, abrasion, and adhesion) are essentially the same. However, we hope to present a clear and compelling argument favoring the prominent and irreplaceable role of in situ experimental techniques as a bridge between fundamental atomistic and molecular processes and emergent behaviors governing tribological contacts. 395 Annu.

“…The atomic nature of wear has been examined for brittle as well as for ductile materials such as the metals already discussed. The anisotropic nature of wear for magnesium oxide [59] and aluminum oxide [60] has been shown. In reference [59] The origin of these dislocation steps at the surface with deformation expose nascent, atomically clean material which can interact with the environment at the surface or a mating solid surface.…”

Should the latter occur the initial step in the formation of an adhesive wear particle has occurred.…”
