FIELD: metallurgy.
SUBSTANCE: composition for obtaining a protective coating on steel parts contains the following components, wt %: aluminium-chromium-phosphate binding substance 30-35, chromic anhydride 5-10, water 12-18, and aluminium powder is the rest. The composition contains aluminium powder with fraction of up to 10 mcm.
EFFECT: invention allows decreasing the hardening temperature of the obtained protective coating and obtaining the coating with high water resistance and high protective ability.
