EFFECT OF ABRASIVE PARTICLE SHAPE ON TWO-BODY ABRASIVE WEAR OF STEEL

Abstract

This paper presents the results of Hardox Extreme steel wear rate testing using an abrasive mass of varying grain shapes. The tests were conducted by the ASTM G65 method using crushed and natural sand with a grain-size distribution of 0.05–2 mm, obtained from a gravel pit. The abrasive materials used in the tests differed in grain shape, while the particle-size distribution was similar. The test results show that the wear rate in crushed sand is four times higher than that in natural sand, which is attributable to the shape of grains and the geometry of their edges.
