What is laser cladding and how does it work?
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.
What are technical characteristics of laser cladding?
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.
What materials are typically used for laser cladding?
The materials used for laser cladding are mainly thermal spraying and thermal welding materials, such as self-fusing alloy materials, carbide dispersion, or composite ceramic materials, which possess excellent wear and corrosion resistance. They are usually used in powder form, and during cladding, flames spray-welding may be employed to achieve a smooth surface with good adhesion to the substrate.
What is the warranty period of laser cladding machine?
The complete machine is under 1-year warranty. Its main accessories and consumables will be replaced depending on their specific service life. We also provide original accessories for global users, with quotes available within 24h and delivery within 3-7 working days.
