“…The magnetic abrasive machining (MAM) method is quite effective when processing flat, shaped, and complex-shaped parts made of various materials. Features of MAM and the ability to control the parameters of the process without interrupting it made it possible to process and assembled parts from dissimilar materials [5][6][7].…”

The influence of the composition and structure of ferromagnetic composite powders on the surface morphology of hard alloys of titanium-cobalt and tungsten-cobalt groups during magnetic-abrasive processing has been investigated. The mechanisms of contact interaction of a ferro-abrasive quasiplastic medium with the surface of hard alloys are established. Ferromagnetic abrasive powders have been developed for the processing of hard alloys. It is shown that a composite powder clad with silicon carbide and diamond grains has a more intense effect on the surface of hard alloy plates. It increases the intensity of the abrasive component and reduces adhesion during the contact interaction of the powder matrix and the hard alloy. The microhardness of the surface layer of the hard alloy increases by 20-47% relative to the initial one, which is associated with the combined action of the ferromagnetic abrasive powders particles and the magnetic field, which cause deformation of the crystal lattice, an increase in the concentration of dislocations, and refinement of brittle phases.

“…Despite the low dynamic loads and the size of the removed chips, with MAM, the material is hardened and softened in the surface layer due to the repeated cyclic mechanical action of the medium on the processed material [5,7,18]. With MAM, chip formation is significantly different from the cutting process with a fixed abrasive.…”
