Question

In nitriding process of heat treatment the steel components are heated in the presence of

Answer 1

Answer :-

In nitriding process, nitrogen is added to the surface of steel parts either using a gaseous process where dissociated ammonia as the source or an ion  process where nitrogen ions diffuse into the surface of components. Nitriding  is the surface hardening treatment.

Gas nitriding develops a hard case in a part at low temperature, without the need for quenching. The process has the advantage of being able to get into blind holes, and also allows for the masking of parts to keep areas which may need further machining soft.
