Abstract

PURPOSE:To form the sulphurized and nitrided layer of superior abrasion resistance and self-lubricity on steel plate surfaces by the nitriding the sulphurizing method by glow discharging in the mixed gases of NH3 and H2S or the mixed gases of at least one kind of H2, Ar, He and NH3, H2S with the iron or steel material as cathode. CONSTITUTION:The iron or steel member to be treated is put in an evacuated vessel to make a vacuum in the vessel, after which hydrogen gas is introduced therein and the material to be treated is raised of temperature to 400-600 deg.C by glow discharging. Next, the gas is substituted with the mixed gases of 95 up to 100% of NH3 and 0.01 to 5% of H2S or the mixed gases of 25-100% of NH3, 0.01-5% of H2S and the rest of at least one of Ar, H2, He. With the member to be treated as cathode, the glow discharge is continued in the gases containing NH3, H2S to let nitriding and sulphurizing the simultaneously effected through ion sulphurizing and nitriding. The sulphurized and nitrided layer of superior abrasion resistance and self-lubricity is formed.
