摘要 |
<p>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°C to about 740°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.</p> |
