That article doesn't make any reference to the depth of penetration of the process, which was my main concern.
Further, while it is true that it can relieve internal stresses and reduce voids and dislocation in the grain structure.
All of the effects such as increased wear resistance, point to more carbon being brought to the surface and the formation of a harder outer case (Case hardening) which I would have though would come at the dentriment of toughness when you're talking about the gearset globally ?
Not against the idea at all just need to know that it will work the way I need to to.
TL;DR basically. Lol.
