Estimation of the Efficiency of Applying Nitrogen Powder Materials in Magnetic Abrasive Processing Technology

The article evaluates the efficiency of applying new diffusion-nitrided ferromagnetic abrasive materials in the technology of magnetic abrasive processing. In this work, the efficiency of processing and the attainable roughness of the processed surface are selected as efficiency criteria. The proposed new powder materials are manufactured by nitriding dispersed metal waste based on 16MnCr5 steel and provide an increase in the productivity of magnetic abrasive processing, an effective decrease in the roughness of the processed surface, and the achievement of a roughness Ra of 0.16 μm. The tests of new nitrided powder materials based on metal waste were carried out in comparison with the most common sintered powder material Fe–TiC.
