Effect of Rheological Properties of a Magnetosensitive Tool on the Friction and Wear of Polished Surface

详细

The results of an experimental investigation on determining the characteristics of a magnetorheological polishing composition prevailing in the course of the abrasive removal of the material of a treated surface have been presented. The similar character of relative rate of material removal in the course magnetorheological polishing and the friction force increment in the course of the model experiment depending on the strength of the external magnetic field has been revealed. It has been shown that, in the course of magnetorheological polishing, a determining role in the abrasive material removal is played by viscoplastic properties of the magnetorheological matrix formed in the magnetic field.
