This paper discusses the grindability of sprayed coatings of Al2O3(-TiO2). The actual grinding action was investigated experimentally by surface grinding using a resinoid diamond wheel with different particle sizes and concentrations.
The maximum height of the grinding surface was lower when the grain size of the wheel was larger and the degree of concentration of the wheel was higher. The abrasion of the grinding wheel was not due to the abrasion by the abrasive grain, but to a selective removal of the combining material during grinding and a reduction of the holding strength of the abrasive grain. This phenomenon was remarkable when the degree of concentration was low.
