Mathematical modeling of the kinetics of counter diffusion during the formation of boron-containing coatings on steels

For the first time, a mathematical model of the kinetics of the formation of diffusion boride coatings on iron has been created, allowing to calculate the increase in the dimensions of parts due to the displacement of the outer surface of the saturated sample. Models of diffusant distribution in boride phases of different chemical composition are obtained. The experimental results confirmed the validity of the developed models.
