Corrosion inhibition of metals (especially iron, zinc, copper, tin and aluminium and in particular mild steel and the zinc surface of galvanized steel) is provided by treatment with an optionally substituted 2-hydroxy-5-alkylbenzaldoxime wherein the 5-alkyl group contains from 7 to 13 carbon atoms. The benzaldoxime may be applied directly or as a solution in an organic solvent or as an aqueous emulsion. The benzaldoxime may be formulated in a surface coating composition. |
