Internal friction characteristics of mixtures of magnetic abrasive powdersin magnetic fields

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