I am working on a failure analysis in the metallurgical lab.
My question to the gear gurus is the following: In a nitrided gear, is there any reason why it would be desirable for the nitride pattern or depth of nitriding pattern to be anything other than uniform around the profile of the gear teeth?
The profile I'm finding is deep on the leading edge of the tooth and very shallow on the trailing edge. I will post dimensions when I have them. This is not what I normally would see for carburized gear teeth and I suspect it may have some role in the failure.
The failure was noted during manufacturing, not during service of it.
Any advice would be greatly appreciated!!!
