ОБРАБОТКА МЕТАЛЛОВ № 2 (67) 2015 15 ТЕХНОЛОГИЯ of the grinding process of microporous coatings by applying a chemically active media that can reduce interaction between coatings and abrasive materials are suggested. New coolants with chemically active substances, passivating the surface of microporous coatings on the round outer grinding operations are tested. A proposal about feasibility of replacing the oil compositions of cutting fluids on aqueous compositions that allow to increase the processing capacity and durability of wheels made of aluminum oxide and silicon carbide, while reducing the height of the microscopic inequalities in comparison with the oil compositions is put. Comprehensive assessment of test results by the rating method showed that the most effective in the round external grinding of microporous coatings on nickel and iron-based is the aqueous solution of emulsol “EPM - 1sh.” Keywords: plasma coatings, abrasive treatment, coolants and lubricants, grinding wheels, cutting forces, tool degradation, surface roughness.
