Abstract
In a surface treatment process for mechanical parts, for conferring on the parts a high resistance to wear and corrosion and a roughness propitious to lubrication, nitriding of the part is followed consecutively by oxidation of the part. The nitriding is applied by immersing the part in a molten salt nitriding bath free of sulfur-containing species at a temperature from approximately 500.degree. C. to approximately 700.degree. C. The oxidation is carried out in an oxidizing aqueous solution at a temperature less than approximately 200.degree. C.
