Abrasive particles used in abrasive jet machining. In AJM, it is assumed that hard abrasive particles participate in material removal action, while carrier gas assists to blow away eroded particles from machining zone. Such abrasives must possess few basic properties for efficient removal of material as well as to get desired quality of cut.
