Conclusions
- 1.
In induction heating of a surfacing alloy with a mixture containing thermally reactive additions an 0.4–2.0 mm thick boron-containing layer is formed on the surface.
- 2.
The addition of thermally reactive additions to the surfacing mixture makes it possible to obtain a hypereutectic structure with a hardness of 63–65 HRC which is 65–75% of the volume of the surfaced metal. This must lead to a significant increase in wear resistance of the treated part.
- 3.
Under production conditions the occurrence of a thermal reaction in surfacing work makes it possible to increase the productivity of the process by up to 15%, to reduce the specific energy requirement by up to 20%, and to improve the ecology of the process as a result of elimination of the use of fluxes.
