Abstract

PURPOSE:To improve abrasion resistance and self-lubricity by forming an ion carburized and nitrided layer on the surfaces of carbon steel or low alloy steel which does not contain any element having strong affinity to N2 then further forming any of an ion sulphurized and carburized layer, ion sulphurized and nitrided layer and ion sulphurized, carburized and nitrided layer. CONSTITUTION:A member of carbon steel or low alloy steel which does not contain any element having high affinity to N2, such as Cr, V, Al, Si Mo or other is put in a vessle. The mixed gases of the least one of H2, Ar, He as a diluting gas and methane base hydrocarbon gas and N2 gas as C source are sealed in the vessel to about 1-10torr, thence with the steel material to be treated as cathode, voltage of 300-1500V is applied between the same and anode to allow glow discharge to occur. An ion carburized and nitrided layer is formed on the steel material surface and further one of an ion sulphurized and carburized layer, ion sulphurized and nitrided layer and ion sulphruized, carburized and nitrided layer is formed thereon through the similar glow discharge. The diluted gas of H2S gas is used as the gas for sulphurizing.
