Boroseliconizing of a low-carbon steel in a dynamic powder mixture

The kinetics of growth of the diffusion zone, formed in the dynamic powder mixture, differs from the kinetics of growth in the stationary mixture by the value of the parabolic growth constant. The difference in the diffusion constants is reflected in the structure and the phase composition of the borosiliconized layer.
The special feature of formation of the phases of the diffusion layers in the dynamic borosiliconizing mixture is the formation of higher silicide phases and also phases of a more complicated composition.
With all conditions being equal, the rate of saturation in the dynamic mixture in borosiliconizing is 1.5–2.0 times higher in comparison with saturation in the stationary mixture.
