 Nitriding


Nitriding is a heat treating process that alloys nitrogen onto the surface of a metal to create a case hardened surface. Three methods are there for nitriding 
           1. gas nitriding 
           2. salt bath nitriding.
           3. plasma nitriding.
Nitriding is a surface-hardening heat treatment that introduces nitrogen into the surface of steel at a temperature range (500 to 550°C or 930 to 1020°F), while it is in the ferrite condition. Thus, nitriding is similar to carburizing in that surface composition is altered, but different in that nitrogen is added into ferrite instead of austenite.  Because nitriding does not involve heating into the austenite phase field and a subsequent quench to form martensite, nitriding can be accomplished with a minimum of distortion and with excellent dimensional control.
