Abstract

Forming of an anticorrosion coating at low cost within a short period of time to thereby facilitate application to general-purpose marine steel structures. There is provided a method of forming an anticorrosion coating, comprising providing steel caisson (1) as a negative electrode and undersea member (3) set in seawater opposite to the steel caisson (1) as a positive electrode and passing a direct current therebetween so as to induce an electrolytic reaction of seawater to thereby form anticorrosion coating (8) on the steel caisson (1) and thus attain corrosion prevention, wherein the current is passed between the electrodes at a current density realizing formation of coating (7) composed mainly of magnesium hydroxide on the steel caisson (1) to thereby produce coating (7) of given thickness, and thereafter the supply of the current is discontinued so as to induce a composition replacement action attaining replacement of the magnesium hydroxide produced in the presence of seawater by calcium carbonate, thereby producing the anticorrosion coating (8).
