Conclusions

  1. 1.

    The structure of plasma-sprayed steel coatings and their strength of adhesion to a substrate are governed to a large extent by the technological parameters of the spraying process. Under the optimum conditions, the resistance to stripping of such coatings equals 325 kg/cm2.

  2. 2.

    During plasma spraying with U8A and PK-2 steel wires, the carbon content changes from 0.79% in the initial condition to 0.63%.

  3. 3.

    During the plasma spraying process, phase transformations take place in the steel, resulting in the formation of quench sorbite.

  4. 4.

    A characteristic feature of the structure of plasma-sprayed steel coatings is its nonuniformity, the carbon content of local volumes of material varying from 0.16 to 0.7%.

  5. 5.

    The presence of phase transformations in high-carbon steels during plasma deposition provides a means of controlling the structure and properties of plasma-sprayed steel coatings.
