Abstract

PURPOSE: To form a superior anticorrosive film on an iron type metal contg. Si> 0.5% by heating the metal to form an inorg. film on the surface and coating an inorg. zinc rich paint after which the metal is dipped in hot water contg. an acidic cpd., taken out, and coated with a finish coating.
CONSTITUTION: An iron type metal contg. Si>0.5% is heated to 700W950°C in an oxidizing atmosphere to form an inorg. film based on iron oxide and iron silicate on the surface and an inorg. zinc rich paint using an alkali silicate as a binder is coated. The metal is then dipped in hot water contg. chromic anhydride, phosphoric acid or other acidic cpd., or sprayed with the water to impregnate the film with the cpd. Thereafter, finish coating is carried out to prevent elution of Zn in the paint, forming an anticorrosive film of superior strength and adherence.
