Patent

CA 2309452

An abrasive article (10) 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 (13, 32). 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.

L'invention concerne un article (10) abrasif comprenant une surface périphérique à laquelle on a ajouté un agent de meulage. Cet agent de meulage est obtenu à partir d'un mélange comprenant un acide et au moins un sel de phosphate métallique inorganique ou un sel de sulfate métallique inorganique. L'acide est sélectionné de préférence de manière que le mélange forme une pellicule. L'article abrasif comprend de préférence des particules (13, 32) abrasives tranchantes. Cet article abrasif améliore l'efficacité du meulage par comparaison aux article abrasifs sensiblement dépourvus de l'agent de meulage décrit, en particulier dans les opérations de meulage du titane. L'invention concerne également un procédé permettant de produire un article abrasif et un procédé permettant d'abraser une surface à l'aide d'un article abrasif.
