Melonite Finish
Melonite Finish
(OP)
My company uses a lot of Melonite QPQ finishes for parts. This process is a bit expensive and I am trying to research alternate processes. Any help or suggestions would be welcome.
Melonite™ and Melonite QPQ™ are thermochemical processes intended for the case hardening of iron based metals. These processes are categorized as molten salt bath ferritic nitrocarburizing. During these processes, nitrogen, carbon, and small amounts of oxygen are diffused into the surface of the steel, creating an epsilon iron nitride layer (e - FexN).

RE: Melonite Finish
I was looking for a process that wasn't based on salt bath nitriding (figuring cost would be similar for similar processes), that will provided for the case hardening we are looking for, with good corrosion protection and dimensional stability.
