Abstract

A range of techniques has been used to evaluate the size and shape of a range of abrasive that have been used to carry out abrasive wear experiments on hardmetals and ceramics. Reasonable agreement was obtained between the results of image analysis size assessment and sieving experiments.
Little difference in shape parameters was seen for the abrasives examined. This was thought to be due to the fact that there was more difference in shape between on asperity and the next, and from particle to particle than there was between the abrasives that were examined.
The effectiveness of using confocal optical microscopy for the 3D analysis of the shape of abrasives was explored; good results were obtained.
Analysis of sand used in the ASTM B611 tests found that a significant fraction of the sand had been broken down in size by a factor of more than ten. The shape of the particles had become measurably less rounded
