Partial pressure in Nitriding potential
Partial pressure in Nitriding potential
(OP)
I want to know what type of pressure is the partial pressure of gas in Nitriding potential = (pNH3)/(pH2)^3/2.
I mean is it static, dynamic or total pressure.
Also how this pressure can be measured in a nitriding furnace for on line control of Nitriding potential.
Link to references will be appreciated.
