Conclusion
As the result of comparison of the service properties of cast magnetic abrasive powders with the same type of structure but different physicochemical properties of the constituents an evaluation was made of the abrasive properties of the latter in polishing of various materials. It was shown that by changing practically only the composition of the solid solution or of the eutectic of the ferromagnetic matrix of the magnetic abrasive powder it is possible to influence both the weight removed and the finish of the polished surface. Similarly the composition of the abrasive inclusions even with the same microhardness may significantly change the polishing indices.
Comparative tests of the carbide- and boride-containing powders showed the advantages of the first in polishing of constructional steel and of the second in polishing of stainless steel and titanium and aluminum alloys.
