Selection of a Nitriding Atmosphere

August 9, 2009

In a process design for control of a nirtiding atmosphere using hydrogen sensors.
Is it better the use ammonia ⇦ this on eBay or Amazon [affil links] & nitrogen atmosphere or an ammonia & dissociated ammonia atmosphere.

Our concern is producing IGN in M50 tool steel, when the nitrogen content is too high.
Thus which of these atmosphere selections would work better with a hydrogen sensor.
