FIELD: chemical industry. SUBSTANCE: suspension contains silicon carbide - 10 to 20 percent by mass, potassium hydroxide - 0.25 to 0.5 percent by mass, dihydrate of tetrametaphosphinic acid (DTMPhA) - 0.25 to 1.0 percent by mass, metacryl 14 (copolymer of methylametacrylate) and methacrylic acid (MMC/MC) - 0.05 to 0.1 percent by mass and water - the rest. MMC/MC is placed in a solution of DTMPhA in an aqueous solution of KOH, and silicon carbide is introduced. Characteristics of metal surface: Ra0,03-0,02 μm (▿11-▿12), planeness (□·103)0,3-0,6 mm. EFFECT: facilitated procedure. 2 tbl
