Dana Corp. is developing a process that carburized a straight bevel gear to a carbon content of 0.8% in 60 fewer minutes than atmosphere carburizing did with an identical straight bevel. The Dana process, called AtmoPlas, uses plasma and microwaves to carburize workpieces at atmospheric pressure. Moreover, in the above test, the atmosphere carburized gear achieved a case depth of 0.035", the AtmoPlas processed gear: 0.045".
