I'm not a chemical engineer so I can only tell you what I understood about
the process. A common hardening method is what is called tuftriding or
ntriding in the UK, no problem except that you end up with lots of diamond
hard dust on the surface and it all has to be taken off with wet and dry and
it takes hours. Ferritic nitro carburise must be a similar process but the
surface is ready to use (apart from a quick wash) - ferrous items are put
into a vacuum furnace with an ammonia atmosphere and a chemical reaction
takes place which fixes nitrogen into the surface. As a secondary use it
also is an excellent rust preventative.
