I want to form iron nitride phases in a iron foil of 300-450 um(micrometer). It's almost impossible to get the nitriding profile so deep by gas nitridng or by plasma nitriding. However, we don't have access to ammonia gas due to safetyor plasma nitriding process. Now, can anyone here, suggest me any process to nitride my iron foil?
If you have any nitrided iron part around, on it there may be some White layer, Fe3N4, which is very brittle and can be easily powderized. You may try to couple your foil with the powder and heat around 550C for couple of hours. If the White layer on the part has been removed previously, you can use the nitrided case as well to couple with your foil (form a diffusion couple). Iron cannot be nitrided in nitrogen N2 gas below few thousand atm pressure.
Please, under no circustances,,intend to use highly poisonous liguid cynide (CN for nitriding). It may be deadly.
Hope it helps.
Hi, do you know this paper about a transition from oxidation to nitriding in a single N2–H2–O2 post-discharge?!
