Abstract	The process of gaseous nitriding is considered to be fully controllable by temperature and the nitriding potential. Most of the commercially used control systems are based on the Lehrer Diagram showing the relation between nitrogen-iron phases, temperature and the partial pressure ratio of ammonia and hydrogen. This is also reflected in the measuring equipment used to determine the nitriding potential. As everyone knows, Lehrer’s phase diagram was created out of a reaction between a set gas mixture of ammonia and hydrogen and pure iron. In industrial nitriding cycles, dealing with real materials and real parts the results often do not match the expectations. The presentation will try to explain the parameters that have to be taken into account and how to measure, set and control the according potentials by giving an insight on the available equipment.
