| Abstract: | With application of the principle of hardening the material through phase transformation by laser, the matrix surface of the stamping die for 9mm tablet was quenched by laser in order to increase the hardness of the matrix surface, to make the metallographical structure finer and to improve shock resistance of the matrix cavity, so as to extend the service life of the die. The experiment result shows that quenching by laser can increase the hardness of the matrix surface by 4-5HRC and extend the matrix life by over 20%. |
