SURFACE TREATMENT FOR STEEL MEMBER

PURPOSE:To work a sliding steel member into a smooth surface reduced in surface roughness by forming a nitride layer and an oxide-enriched layer composed essentially of Fe3O4 on the surface of a sliding steel member and then polishing the surface by a mechanical means. CONSTITUTION:The surface of a...

Zusammenfassung:	PURPOSE:To work a sliding steel member into a smooth surface reduced in surface roughness by forming a nitride layer and an oxide-enriched layer composed essentially of Fe3O4 on the surface of a sliding steel member and then polishing the surface by a mechanical means. CONSTITUTION:The surface of a steel member, such as piston rod for hydraulic bumper, is worked, e.g. to
