FIELD: metallurgy. n SUBSTANCE: invention relates to producing converting or passivating coat onto metal surfaces. Composition for proposed coat comprises particles of colloid oxide, ureido-silane, hydrolysed or partially hydrolysed ureido-silane, or ureido-silane condensate and water. Proposed method comprises bringing the surface in contact with composition comprising particles of colloid oxide, or colloid silicon oxide, ureido-silane, hydrolysed or partially hydrolysed ureido-silane, or ureido-silane condensate and water, and, not obligatorily, alkoxylated silane or hydrolysed alkoxylated silane. n EFFECT: higher corrosion resistance of pure or painted metal and adhesion properties. n 10 cl, 10 tbl, 6 ex |
