ABSTRACT OF THE DISCLOSURE: A method for forming a carbide layer of a V-a group element of the Periodic Table on the surface of an iron, ferrous alloy or cemented carbide article in a treating molten bath, comprising preparing the treating molten bath composed of boric acid or a borate and a V-a group element, immersing the article in the treating molten bath and applying an electric current to the treating molten bath with said article being used as the cathode, thereby forming, a very hard carbide layer of said V-a group element of the surface of said article. The method of this invention can form quickly a uniform and dense carbide layer on the surface of the article and can be carried out in the open air.
