Abstract

PURPOSE: To improve the corrosion resistance and wear resistance by a method wherein KBF4 is used as an accelerator in chromizing treatment so that generation of nitrogen or the like are avoided and the surface layer of a pin of the chain is covered by ferrite α.
CONSTITUTION: A roller chain 1 comprises two steel pin link plates 2 and roller link plates 6 which are connected through a pin 3. The pin 3 is made of a medium carbon steel or a medium carbon alloy steel. After the pin is heated together with metalic chrome and KBF4 for a prescribed period, it is air cooled, hardened and then tempered under a prescribed temperature, so that the substrate phase of a chrome diffused surface layer 12 of the pin may consist of the ferrite α. Also in this substrate phase are diffused numerous minute granular chromium carbide. Thus the pin 3 or other bearing members is improved in corrosion and wear resistances.
