While achieving nitrocarburizing iron-chromium binary alloys. The objective was to follow the evolution of the microscopic properties of the layers obtained after nitrocarburizing treatment and to study the microstructural changes and the microhardness as a function of the chromium content chosen. All the results obtained have allowed us to observe that the kinetics of nitrogen diffusion depend strongly on the chromium content. The diffusion depth of the nitrogen and the thickness of the white layer are lower than the chromium content is high.enKineticThicknessDiffusionChromiumNitrocarburizingIntervention
