  • Surface treatment process for mechanical parts subject to wear and corrosion
    Patent number: 6645315
    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° C. to approximately 700° C. The oxidation is carried out in an oxidizing aqueous solution at a temperature less than approximately 200° C.
    Type: Grant
