Conclusions

  1. 1.

    Laser hardening of articles made of structural and tool steels may be accompanied by buckling which depends on thermal expansion of the surface layer, formation of martensite within it, residual stresses, and nonuniform structure through the cross section. The amount of deformation is affected by geometric dimensions, hardened layer thickness, steel structure, and properties (yield point) after prior heat treatment.

     
  2. 2.

    By varying the coordinate sequence for laser beam treatment it is possible to reduce article deformation significantly. The optimum schedule is uniform and symmetrical filling of the surface being treated by “spots” of hardening.
