Nitriding Iron at Lower Temperatures
  • Abstract
      The microstructure in the surface layer of a pure iron plate was re.ned at thenanometer scale by means of a surface mechanical attrition treatment that generates repetitive severe plastic deformation of the surface layer. The subsequent nitriding kinetics of the treated iron with the nanostructured surface layer were greatly enhanced, so that the nitriding temperature could be as low as 300 oC, which is much lower than conventional nitriding temperatures (above 500 oC). This enhanced processing method demonstrates the technological significance of nanomaterials in improving traditional processing techniques and provides a new approach for selective surface reactions in solids.
