Abstract
The present study shows an evaluation of the effects of strain hardening on the kinetics of the nitriding thermochemical treatment in alloyed ferritic stainless steels AISI 430 and AISI 439 for different degrees of plastic deformation. The processes of application of the gas nitriding, in salt baths and plasma were performed on these alloys. The layer thickness was larger for the process of nitriding gas. Note also that the nitrogen concentration reduces with the depth of the nitrided layer as it comes near to the base metal. On the other hand, carbon is pushed inside of the sample, promoting decarburization in the region enriched in nitrogen and an accumulation in the regions just below to the nitride layer. In general, note that the ferritic matrix (Fe–Cr) and the formation of chromium nitride (CrN) in samples of AISI 430 and AISI 439 which suffered plasma nitriding and gas. In addition to this compound, it was possible to identify the presence of Fe4N and Fe3N. In the samples of AISI 430 and AISI 439 nitrided in salt baths, it can be observed that the nitrided layer consists in the ferritic matrix (Fe–Cr) with predominance of precipitates (FeCr)2N and without presence of peaks of CrN.
