Research on laser surface treatment for plastic die steel
Laser surface treatment technology can selectively treat the surface of the workpiece,while maintaining sufficient toughness and strength of the workpiece as a whole,the surface ob-tains high and specific performance,so it has application potential in improving the structure and performance of plastic die steel.Based on this,on the basis of a large number of literature studies,the research progress of laser surface modification technology in the microstructure and proper-ties of plastic die steel was described,mainly from the laser melting,laser cladding,laser alloying,and laser hardening technology,and its advantages and disadvantages were summarized and ana-lyzed.Finally,the possible development directions in the future were proposed in order to provide reference and guidance for the laser surface treatment technology for plastic die steel and the de-velopment of equipment.
