• the laser hardening process can be used for fully finished parts, • production cost can be reduced dramatically, • time of production can be shortened significantly • material cost can be reduced by the possibility of using cheaper material • quick, instant method • easily repairable, repeatable • only the surface will be modified, the core remains unchanged • compound structure can be reached with tough core and hard surface • the hardness of the the surface can be much higher than in the case of volume hardening • there is no distortion, deformation • in the deeper layers there is no recrystallization and grain coarsening • can be used selectively and precisely
• relatively expensive because of the use of expensive technique, • single stripe or spot can be used at one time • back tempering at overlapping • not every kind of material can be hardened effectively • need of quality control and lab tests |
