Project introduction

Laser surface heat treatment refers to the heat treatment of the surface of metal materials using the thermal effect generated by the high energy of the laser beam, which can help improve the wear resistance, corrosion resistance, fatigue resistance and impact resistance of the metal surface. The advantages of laser treatment are no pollution, local surface treatment, small pressure, small deformation, and broad application prospects.

According to the type of material characteristics, adjust the laser power density, laser irradiation time and other process parameters, can be divided into laser surface quenching (phase change hardening), laser surface melting, laser surface alloying laser surface treatment. The solution is widely used in the automotive industry, in many automotive key parts, such as cylinder block, cylinder liner, crankshaft, camshaft, exhaust valve, valve seat, rocker arm, aluminum piston ring groove and so on almost all can be laser heat treatment.
