I have little to do with chemistry and my only background is the inorganic chemistry I learned at school when I was 13-14 years old.
I need to have a basic understanding of the nitrating process (for an automation engineering application, more precisely an automated furnace used for nitrating iron or steels parts with the purpose of improving their mechanical and chemical properties).
A few things are not so clear for me:
- What is the chemical formula of the iron lattice mixed with nitrogen atoms (see the picture)?
- What is the unwanted white layer that I understand forms on the surface of the metal part treated with dissociated ammonia?
- What is this dissociated ammonia?
