摘要

FIELD: metal protection against corrosion. SUBSTANCE: coating is formed by method of microarc oxide coating at anode current density 5-25 A/dm² from alkaline electrolyte after preliminary application of film on the article surface. Film has the following composition, wt.-%: aluminium powder ПАП-1 or ПАП-2 3-18; dye with sealer enamel ХФ at the ratio 1:1 - the rest. EFFECT: increased effectiveness of coating. 1 tbl
