MAKING OF A STEEL COMPONENT BY NITRIDING

摘要

A component formed of interstitial free steel is heated in a gaseous atmosphere containing 15% by volume of a nitrogen doner, e.g. ammonia, at about 500 DEG C. to about 740 DEG C. for about 30 minutes to about 4 hours to form an epsilon iron nitride surface layer, and a layer of nitrides of trace alloying elements below the surface layer.
