Paper 24: Influence of the Hardness of Abrasives on the Abrasive Wear of Metals

Abstract
Abrasive wear tests were carried out using the abrasives carborundum, corundum, garnet, flint, and glass on a wide range of metals and alloys. The results obtained show that the abrasives each have an effective hardness which defines the maximum hardness of a metal which it will abrade; this value is different from its measured hardness. Further, a relationship has been derived of the form V = KWL log Ha/Hm which enables the volume V of abrasive wear of a metal to be calculated from a knowledge of its hardness Hm, the effective hardness of the abrasive Ha, the abrasive load W, and the length L of the abrasive path; the expression also involves a constant which is evaluated by experiment.
