High energy beam heat treatment of roller seals: a local surface modification technique. The heat sources used are laser, electron beam, ion beam, electric spark, high-frequency induction shock, solar energy and synchrotron radiation. Improve the fatigue strength of the workpiece.

First, high-energy beam heating is non-contact heating. The heat affected zone is small; The heating and cooling speed of the high-energy beam is very fast, and the thermal stress is very small, so the workpiece deformation is small. Austenite growth and diffusion of carbon and alloy atoms are suppressed.

Second, due to the fast heating speed. Profiles of both refined and ultra-refined organizations can be obtained. Because of the small area of the high-energy beam.

Third, the high energy beam heat treatment is punished by the workpiece itself cooling and quenching. The metal's own heat capacity is sufficient to quench the treated surface, ensuring the completion of martensite transformation and obtaining cryptocrystalline martensite. Quenching can also suppress the precipitation of carbides, thereby reducing the influence of the brittle phase

Fourth, residual pressure stress occurs in the metal profile of high-energy beam heat treatment. Therefore, the heating speed is fast, and the cooling speed is also fast.

5. High power density and short operation time. The superheat and supercooling degree are greater than that of conventional heat treatment, and the general hardness after treatment is 5~10HRC higher than that of conventional treatment. High-energy beams have small spots.
