摘要：
Die service life improvement is an important problem in high-pressure die-casting industry. Experiment results on die steel shows that biomimetic laser-remelting process provides a promising method to improve the service life of die-casting die. A casting with uneven wall thickness was selected and problems existing in die-casting production were analyzed. The corresponding die-casting die was processed by biomimetic laser-remelting process. The application result indicates that the service life of the die processed by biomimetic laser-remelting process has been increased from 12,000 to 28,000 shots, which is more than twice that of no processed one under real high-pressure die-casting conditions. The application of laser-remelting process provides desirable micro-structural changes in biomimetic units, which induces the intensified particles effect for improving the service life.
