摘要： A method and treating material are presented for forming a mixed-carbide layer of at least one Va-Group element and of chromium on the surface of a carbon-containing ferrous-alloy material. A molten treating bath is prepared by introducing one or more Va-Group elements in oxide form and chromium in metal or alloy form or by introducing one or more Va-Group elements in metal or alloy form and at least one chromium oxide into a molten bath composed of boric acid, of at least one borate or of a mixture thereof. An article of carbon-containing ferrous alloy is immersed and maintained in the molten treating bath until a mixed-carbide layer is formed on its surface. The mixed-carbide layer formed on the surface of the article is very smooth, wear resistant and high-temperature-oxidation resistant.

摘要： A surface layer which is composed of the carbonitride of molybdenum is formed on an article made of iron or an iron alloy by heating the article in the presence of a material containing molybdenum and a treating agent. The treating agent may be composed of at least one of the cyandides and cyanates of alkali metals and alkaline earth metals. The layer adhering closely to the article can be formed efficiently at a temperature which is so low that virtually no thermal strain may develop in the article.

摘要： A layer of a nitride or carbonitride containing at least one of chromium, Group Va elements, titanium and zirconium is formed on the surface of an iron alloy material which has been nitrided. The layer is formed by heating the iron alloy material at a temperature not exceeding 700.degree. C. with a material containing at least one of chromium, Group Va elements, titanium and zirconium and a treating agent. It is a dense layer bonded tightly to the iron alloy material. As a low temperature not exceeding 700.degree. C. is employed, no large amount of heat energy is required, nor is any thermal strain produced in the iron alloy material.
