Conclusions

  1. 1.

    Boride coatings can be obtained during crystallization of steel castings by using high-melting boron compounds soluble in the liquid metal.

  2. 2.

    The mechanism by which boride coatings are formed on the metal with a liquid matrix is based on the wetting and solution of boron carbon particles, with subsequent crystallization of the boron-rich alloy.

  3. 3.

    The structure and distribution of boron through the depth of the boride coating obey the impurity distribution law.

  4. 4.

    The distribution of boron in the surface layer is affected most by the crystallization rate.
