Alloy Depletion

[rms1956]

thread330-228257

I stumbled upon this thread today and was wondering if anyone else has had success with the creation of Alloy Depletion.

We are going to use this as training material and would like to create a fairly uniform layer of Alloy Depletion on 718 material.
We have both vacuum and conventional furnaces available but would prefer to use vacuum. The thought there would be that vacuum may yield a more uniform layer.
We will probably be using 3/8-1/2" diameter bar stock that has been ground as a starting point.


Thanks

People don't want alloy depletion- they want to detect its presence so the part can be rejected or the layer removed by material removal.

I realize that. That is the basis for the training that I had mentioned.

I know I can create it in a conventional furnace, i have been successful at that already. This time I am trying to create a very precise amount that is uniform in depth and I was wondering if anyone has had success doing this and if so if a vacuum furnace might be better choice for the experiment.
