Abstract
The mechanism by which the particles of a magnetoabrasive powder disintegrate depends on their structure and determines the service performance of the material. The disintegra tion of the particles of the sintered Zh15KT material involves the plucking out of the abrasive component and its removal from the machining space. Under these conditions, the fall in the fraction of the abrasive component in the polishing powder and the resultant decrease of the mechanical wedging forces lower the pressure which the Zh15KT particles exert on the work surface and have an adverse effect on the operating performance of the powder as a whole. The particles of a cast material cease to be effective mainly through attrition. As their nonporous matrices possess high hardness and strength and contact be tween the magnetic matrices and the abrasive over their interfaces is continuous, the service life of a cast powder is much (more than twice) longer than that of the sintered Zh15KT powder agglomerates, in which, because of their high porosity, contact on the interfaces between the iron and titanium carbide particles is discontinuous.
