| Abstract: | Experiments have been done on the friction in powder magnetic-abrasive tool made up of mixtures of ferroabrasive powders of various types, which differ in composition, properties, and particle size and shape. Regularities are established for the coefficients of internal friction between layers in mixtures. A model relationship is proposed for the structuring of a magnetic abrasive tool containing a powder mixture.
