Heat Treatment with the Use of Highly Concentrated Energy Sources

Conclusions

  1. 1.

    The life of high-speed steel tools may be increased significantly as the result of laser treatment.

     
  2. 2.

    Positive results are obtained only after treatment of tools with certain pulse power densities, the values of which must be determined in each specific case.

     
  3. 3.

    The optimum values of laser radiation pulse power density must be selected on the basis of the structure of the steel in the irradiated zone, which must be a martensite-carbide mixture formed as the result of secondary hardening occurring under the action of the laser pulse.

     
  4. 4.

    Deviations from the optimum conditions of laser heat treatment lead to loss of strength of the cutting edge and poorer tool service properties.
