High-end equipment requires extremely high surface performance from its components. Surface strengthening methods such as induction, shot peening, and rolling are hard to meet the application demands of high-end equipment. Laser surface quenching uses a high-energy laser beam to irradiate the workpiece surface, rapidly raising the temperature above the phase transition point. Laser quenching technology has higher processing accuracy, a lower probability of processing deformation, greater processing flexibility and produces no noise or pollution. It has been widely used in the metallurgical, automotive, and mechanical manufacturing industries, and is suitable for heat treating various types of components.With the development of laser technology and cooling system, more efficient and powerful equipment can automatically complete the entire heat treatment process. Laser quenching not only represents a new hope for workpiece surface treatment, but also represents a new way of material s...
