ABSTRACT:
A process for producing a magnetite-coated electrode which comprises kneading an iron oxide powder, water and an organic binder under pressure sufficient to prepare a molded article, baking the molded article in a gas atmosphere mainly composed of a member selected from the group consisting of carbon dioxide and steam to prepare a magnetite sinter having an Fe to 0 ratio of 3:3.7 to 4.0, pulverizing the sinter to prepare a powder, and subjecting a metallic substrate to plasma spray coating, plasma jet spray coating, explosive spray coating and water plasma spray coating by making use of the powder as the spray coating source in a neutral gas atmosphere to form a magnetite coating on the surface of the metallic substrate.
