The main advantages of laser strengthening technology are
(1) The structure of the hardened layer is refined, and the hardness is higher than that of conventional quenching.
(2) The heating speed is extremely fast, the cycle is short, the efficiency is high, the cost is low, and the process is highly automated.
(3) For special parts such as groove walls, small holes, blind holes, and the inner wall of the cavity, any part can be treated as long as it can be irradiated by the beam.
(4) Hardening of local surface of large parts and hardening of complex shapes.
(5) The depth of the quenching layer can be precisely controlled.
(6) To achieve self-cooling quenching, no quenching medium such as oil or water is required.
