Abstract
A method and treating material are presented for forming a mixed carbide layer of Va-Group elements on the surface of a carbon-containing ferrous-alloy material. The molten bath is made by introducing one or more oxides of Va-Group elements and one or more metals or alloys of Va-Group elements (other than the elements forming the oxides) into a molten bath composed of boric acid, a borate or a mixture thereof. The mixed carbide layer formed on the surface of the article is very smooth, wear resistant and corrosion resistant.
