FIELD: processes and apparatuses for working internal surfaces of revolution, possibly restoration works. ^ SUBSTANCE: method comprises steps of working part-anode by means of hone-cathode having metallic cathode members of anti-friction material; using liquid glass base working liquid; working surface at modes preventing occurring of while layer; then applying anti-friction coating due to rubbing by means of working cathode members when technological current is cut off; using working liquid containing, mass %: glycerin, 10 - 30; sodium chloride, 1 - 10; liquid glass (specific gravity 1.15 - 1.3), the balance. ^ EFFECT: enhanced wear resistance and running in capability of internal surfaces of revolution due to lowered crumbling out and additional anti-friction coating. ^ 2 cl, 1 tbl, 1 ex |
