Study of phase composition and defective state of the gradient structures of borated steels 45 and 5ХНВ

The article reveals methods of electronic diffraction and raster microscopy and a method of X-rays analysis, which study gradient structure of steels 45 and 5ХНВ borated with saturated coatings. The quantitative assessment of the fine structure of steels and phase analysis of distancing from the borated surface are worked out. The classification of the layers of the gradient structure and the mechanism of formation of phases are given in the article.
