Chemicothermal Treatment


Surface hardening of Fe−Ti alloys by nitriding is best with a titanium content not exceeding 1.3–1.5%. This produces a case with a high microhardness and good adhesion to the base metal. In alloys with a higher titanium content the amount of nitrogen dissolved in nitriding results in a sharp increase of the volume, embrittling the case and causing cracks.
