Abstract
Die service life improvement is an important problem in highpressure diecasting industry Experiment results on die steel shows that biomimetic laserremelting process provides a promising method to improve the service life of diecasting die A casting with uneven wall thickness was selected and problems existing in diecasting production were analyzed The corresponding diecasting die was processed by biomimetic laserremelting process The application result indicates that the service life of the die processed by biomimetic laserremelting process has been increased from 12000 to 28000 shots which is more than twice that of no processed one under real highpressure diecasting conditions The application of laserremelting process provides desirable microstructural changes in biomimetic units which induces the intensified particles effect for improving the service life
