Scientific novelty
The invention relates to installations designed for creating diffusion metallic coatings on steel products via chemical-thermal treatment to improve physicochemical and mechanical properties, and can be used in a wide range of industries.
Advantages
The invention differs from similar devices by a simplified design that streamlines and accelerates the technological process of diffusion layer formation; reduction of equipment costs due to the possibility of using open shaft furnaces instead of vacuum ones with protective atmosphere support systems. The technology is waste-free; if the required concentration of the saturating element or complex of elements (diffusants) in the Pb-Bi eutectic-based transport melt decreases, the concentration can be replenished, and the number of cycles is virtually unlimited; evaporation of transport melt components is completely eliminated by applying a glassy layer consisting of fluxes or salt melts to the surface.
Commercial implementation
The developed device is oriented towards the Russian Federation market as part of the import substitution program, rationalization, and implementation of modern materials and progressive technologies to ensure specified product quality and high production efficiency.
