Abstract
FeSi(3.2%) and FeSi(2.1%)Al(0.5) sheets are annealed in a fluidized-bed fur nace following a nitriding thermochemical treatment. The nitrogen diffuses following an exponential law. Progressive prepolishings of the surface laye r and the corresponding Mossbauer spectra lead to identification and locali zation of the different phases present in the sample. The surface microhard ness of the nitrided sample is higher compared to the sample treated conven tionally. (C) 2000 Elsevier Science B.V. All rights reserved.
