| Abstract: | Utilizing different laser technology parameters to go on the laser phase transformation hardening test of two automobile mould material surfaces of cast-iron CrMo and Cr12, we studied the micro-hardness distribution situation of the laser hardening layer in the directions of cross and longitudinal, as well as the change of the institutional construction of the hardening layer. The results indicated that using laser quenching in material can greatly improve the hardness of the surface; at the same time, the model surface crackles can be eliminated, thus the service life of the automobile moulds can be improved effectively. |
