COMPOSITE MATERIAL FOR COATING Russian patent published in 2009 - IPC C09D1/02 C09D5/08 

Abstract RU 2355725 C2

FIELD: chemistry.

SUBSTANCE: invention concerns composite material for surface coating for units and parts of aggregates, machines, devices requiring corrosion protection and operating for long time in high-temperature (up to 500°C) flow of natural gas combustion products, represented mainly by water and carbon dioxide (CO2), e.g. for gas turbine elements. Composite material includes the following components at indicated ratio, in wt %: 53.6-68.4 of aluminium powder filler and 46.4-31.6 of binder. Liquid glass with 1.40-1.45 g/cm3 density and 2.85-3.05 modulus or its aqueous solution with 1.12-1.18 g/cm3 density and 2.85-3.05 modulus is used as binder.

EFFECT: enhanced corrosion and adhesion resistance of coating operated in conditions of cyclic high-temperature load up to 500°C.
