Quality gear manufacturing depends on controlled tolerances and geometry. As a result, ferritic nitrocarburizing, DynaBlue(TM) has become the heat treat process of choice for many gear manufacturers. The primary reasons for this being the preferred choice are: 1) The process is performed at low temperatures, i.e. less than critical, 2) The quench methods increase fatigue by up to 125% without distorting. DynaBlue is used in place of carburize and hardening, carbonitriding, nitriding or in conjunction with conventional and induction hardening and, 3) Establish gradient base hardnesses, i.e. eliminate egg shell effect on TiN, TiAIN, CrC, etc. In addition, the process can also be applied to hobs, broaches, drills and other cutting.
