INGREDIENTS TO PRODUCE CORROSION-RESISTANT AND HEAT-RESISTANT COATINGS ON PARTS OF STRUCTURAL STEELS AND HEAT-RESISTANT ALLOYS BASED ON NICKEL

摘要

FIELD: metallurgy.;SUBSTANCE: composition contains the following ingredients wt %: 30-35 of aluminium-chromium-phosphate binder, 12-18 of water, 2-3 of chromic anhydride, 1-3 aluminium hydroxide powder, 10-22 aluminium- silicon powder, and the rest is aluminium powder. Powders of aluminium hydroxide, aluminium - silicon, aluminium, have a fraction of up to 10 microns.;EFFECT: composition provides a corrosion-resistant and heat-resistant coating on the components of structural steels or heat-resistant alloys based on nickel, including the large components, operating for long terms at high temperatures in the context of salt corrosion.;2 cl, 3 tbl
