Abstract

A method of protecting ferrous metal surfaces against corrosion due to contact with hot furnace gases comprises spraying the surfaces with a thin coating of aluminium and subsequently treating the aluminium surface with a partly hydrolyzed organic silicate. The surfaces may be sprayed with aluminium to a thickness of .002" to .01" and then treated with a solution made by shaking together for 20 minutes, 81 parts by volume industrial methylated spirit; 30 parts 0.06 per cent hydrochloric acid and 1 per cent ethyl silicate and then adding a further 160 parts of ethyl silicate, the solution being used after standing for 1-6 hours.
