Laser cladding is an important method for surface modification of materials. It uses high-energy laser beam to irradiate the metal surface for rapidly melting, expanding and solidifying. The cooling rate typically reaches 102 to 106℃/s, then, a layer of material with special physical, chemical or mechanical properties will take its shape on the substrate surface, thus creating a new composite material. This process can compensate for the lack of high performance in the base material and significantly improve substrate surface properties in terms of wear, corrosion, high temperature and oxidation resistance.
Compared to commonly used methods such as overlay welding, thermal spraying and plasma spraying, laser cladding has the following advantages:
* The heat-affected zone is small, resulting in minimal deformation of workpiece and a high yield of cladding.
* The layer has fine crystal grains and dense structure, leading to relatively high hardness and better wear and corrosion resistance.
* Due to short duration of laser action, the dilution rate of cladding layer is low, which causes a smaller amount of material melted (typically 5%-8%). Therefore, it is possible to achieve the desired composition and properties even with a thin cladding layer, and to produce new structural features such as metastable phase, ultra-dispersed phase and amorphous phase.
* It is easy to automate the laser cladding, and the quality of cladding layer is always stable.
