What ist the nitriding potential?
The nitriding potential is thermodynamically defined by:
where „pNH3” and “pH2” are the partial pressures of the ammonia and hydrogen gases respectively. This potential defines the possibility of creating the nitrogen layers of determined structure. Generally – the higher potential is the resulting phases richer in nitrogen are. The phase structure of nitrogen layers as a function of potential and temperature is presented in Lehrer’s chart.
