ABSTRACT:
An abrasive article is provided which includes a peripheral surface formed comprising a grinding aid. The grinding aid is formed from a mixture including an acid and at least one of an inorganic metal phosphate salt or an inorganic metal sulfate salt. The acid is preferably selected so that the mixture forms a film. The abrasive article preferably has sharp abrasive particles. The inventive abrasive article improves grinding efficacy, particularly in titanium grinding processes, as compared to abrasive articles that are substantially devoid of a grinding aid of the present invention. Also provided is a method for making an abrasive article and a method of abrading a surface with an abrasive article.
