Abstract
The invention provides a laser hardening method capable of preventing adjacent already-hardened layers from being annealed. In the laser hardening method of the present invention, conduits C.sub.1, C.sub.2 and C.sub.3 are processed in advance midway between pitches P.sub.1 along which a hardening nozzle 190 performs overlap hardening. After moving the nozzle 190 along a center line L.sub.3 to process a hardening layer H.sub.23, the nozzle 190 is moved in parallel for a single pitch P.sub.1 to perform hardening of a hardening layer H.sub.24. Thermal energy E.sub.1 of the laser beam LB is also irradiated toward the direction of the hardening layer H.sub.23, but it is blocked by the conduit C.sub.3 that prevents the laser beam from annealing the hardening layer H.sub.23.
