Nitrided case hardness profile
Nitrided case hardness profile
(OP)
I want to get a quatitative measurement of hardness in the total case of a Nitrided specimen so that I can draw a profile and compare specimens on the basis of their hardness profile resulting from different Nitriding potentials and Furnace temperatures. Can anybody guide me?

Also possible is the creation of deiffusion profiles by the fundamental thermodynamics of the system.

The reason for my suggesting going to a competent metallurgical lab is that they have the equipment and expertise to obtain this data for you. The cost should not be that expensive to obtain only the microhardness traverses, you could review the results yourself and plot them on a graph, in lieu of having a professional engineer at the lab do this.

Of course, you have to measure the hardness with Vicker (for normal layer thickness up to big thickness, indentation load 100 - 500 g, dependent on hardness value) or Knoop hardness for thin layer. You can better use Electron- Microprobe-Analyse (EMP)to get the N-distribution across your nitrided case, but it's expensive.
Good luck
