TL;DR: In this paper, 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.

TL;DR: In this article, the friction, wear and surface microhardness of Al-4 wt. % Cu were measured during abrasion and their dependence on age-hardening and degree of workhardening was investigated.

TL;DR: In this paper, the friction and wear properties during abrasion of compressed compacts made from ball-milled graphite powder are shown to vary systematically with the pressure of compaction.

TL;DR: In this article, the surface structure of abraded materials is described, mainly as it is shown, very sensitively, by electron diffraction at grazing incidence, and the presence, nature and orientation of abrasive particles embedded in the surface, when bonded abrasives are used, is indicated.

TL;DR: In this article, an analysis of the friction, wear and surface microhardness data for the abrasion of Al-4wt.% Cu, presented in a previous paper, is carried out in terms of the estimated ratio d / Λ of the precipitate particle diameter to the particle separation during age-hardening at room temperature and at 165°C.
