The kinetics of growth of the boride layer in the boronizing of carbon steels from EKABOR 3 powder is studied. Relations between the thickness of the boride layer and the parameters of the process, i.e., the temperature and the duration of the boronizing operation, and the composition of the saturated steel are derived. The morphology and the types of the borides are determined by the methods of light microscopy and x-ray diffraction. The parameters of the Arrhenius equation for the kinetics of boronizing are computed. The contour diagram obtained for the variation of the thickness of boride layer makes it possible to determine the size of the layer from data on the parameters of the process.
