Abstract
A method of producing an electrode by applying onto a core material a solution of at least one metal salt and subjecting the resultant core material to a heat treatment in a heating zone, characterized in that said heat treatment comprises continuously elevating the temperature of the resultant core material to a temperature of about 400.degree. to 700.degree. C. over a period of about 5 minutes to 2 hours, while blowing air into the heating zone to obtain a coated electrode. The coated electrode produced according to the method of the present invention is excellent in adherence of the coating to the core material and has long life due to low losses of the coating during use.
Claims11
A method of producing an electrode which comprises applying to the surface of a corrosion-resistant electroconductive core material a solution of at least one metal salt capable of forming an electroconductive substance by heat treatment, and subjecting the resulting coated core material to a heat treatment in a heating zone, said heat treatment comprising continuously elevating the temperature of said resulting coated core material to about 400.degree. to 700.degree. C. over a period of time of about 5 minutes to 2 hours while blowing air into the heating zone at a rate of at least about 0.8 m.sup.3 /hr per 1 m.sup.2 of the projective area of the core material and rapidly removing gaseous products being produced from the surface of said heat treated coated core material.
