Diffusion formation of boride phases on the iron surface

The composition, structure, and size of a coating formed as a result of the interaction between iron and a sodium tetraborate melt with additions of boron and silicon carbides have been determined using electron-probe X-ray microanalysis, X-ray powder diffraction analysis, and optical microscopy.

Description
Summary:The composition, structure, and size of a coating formed as a result of the interaction between iron and a sodium tetraborate melt with additions of boron and silicon carbides have been determined using electron-probe X-ray microanalysis, X-ray powder diffraction analysis, and optical microscopy. The main regularities of the diffusion in multiphase systems have been considered. The rate constants of the growth of the phases under investigation and the parameters relating the reaction rate to the diffusion and thermodynamic characteristics of the Fe-B system have been determined.
