Plasma nitriding pulse shape

Dear Sir:

I am using a plasma nitriding equipment for hardening of low alloy steel at a temperature of 500 degree C(±1 degree C) measured on the surface. The pulse duration is 60 micros. I would like to know if the shape of the plasma pulse has any affect on the final properties of the surface.

Thank you,

Does your equipment allow you to change the shape of the pulse? If it does, you can do trials with different shaped pulses and check for any differences in the hardened layer. A few direct tests will be worth more to you than opinions formed at a distance.
