Abstract

The transformation of aragonite to calcite has been used to provide an indication of the thermal history of debris and the surface of aragonite during abrasion on 320 grade silicon carbide papers. The temperature rise of debris was estimated to be 500°–600°C whereas the specimen surface temperature was considerably lower. This supports the view that the mechanism of material removal during the abrasion of non metallic materials is essentially similar to that occurring in metals.
