| Abstract: | Techniques of laser surface heat treatment,especially laser glazing and laser impact quenching,are major applications of laser procession and also the mark indicating laser application enters the second generation. Laser glazing could make some special alloys amorphous metal glass which was used widely as tough,supeccouductive,magnetic and corrosion resisting materials laser impact quenching could make shot peening effect and prestressed surface so as to improve the microstructure of materials and make materials excellent metallurgical properties. |
