It was found that in both variants of boriding, upon preliminary activation with the powder composition, the morphology of the thermodiffusion layer changes, which is expressed in a decrease in porosity, in particular in the subboride layer, and in a decrease in the needle-like structure traditional for boriding. As a result of pre-treatment, the thickness of the diffusion layer increases by 20 ... 50%, this is especially noticeable for high-temperature borating. The proportion of the high-boron FeB phase in the layer increases, which indicates an intensification of the diffusion and reaction stages in the metal.
