Abstract

PURPOSE: To enhance the galling and wear resistances by combining an iron material subjected to sulfurization nitriding with an iron material obtd. by plating a material having a specified Vickers hardness or above at the surface with Cr.
CONSTITUTION: An iron material subjected to sulfurization nitriding is used as a fixing piece. The sulfurization nitriding is conducted by immersion in a salt bath contg. cyanide, urea and potassium sulfide as principal components. On the other hand, an iron material obtd. by plating a material having ≥250 Vickers hardness at the surface with Cr is used as a movable piece.
