Conclusions

  1. 1.

    The phase composition and microhardness of zones of laser hardening of steel alloyed with boron are determined basically by the amount of boron containing coating, the pulse energy of the laser radiation, and the position of the focal plane of the output lens of the optical system of the installation relative to the surface of the specimen.

  2. 2.

    Alloying the hardened zones with boron yields better mechanical properties than laser heat treatment without saturation, and it may be recommended for parts subjected to wear in operation.
