Principle of Diode Laser Cladding Technology

Diode laser cladding works by using a focused laser beam to melt a thin layer of the base material and simultaneously deposit metal powder or wire, forming a dense, metallurgically bonded coating.Basic PrincipleDiode laser cladding is a laser-based surface engineering process in which a high-energy laser beam is focused on the surface of a component to create a localized molten pool. Metal powder or wire is delivered into this pool, where it melts and mixes with the substrate. As the molten material solidifies, it forms a dense, metallurgically bonded coating that is strongly adhered to the base material, providing superior wear, corrosion, and heat resistance compared to conventional coatings ( ).Process StepsLaser Beam Focusing: A diode laser generates a high-energy beam with a uniform top-hat intensity profile, which is directed onto the substrate surface ( ).Substrate Melting: The laser energy melts a thin layer of the base material, forming a small molten pool.Material Deposition: Metal powder or wire is fed into the molten pool, where it melts and mixes with the substrate.Solidification: The molten pool rapidly cools (10³–10⁶ K/s), forming a gradient coating with minimal dilution and strong metallurgical bonding ( ).Layer Formation: The process can be repeated in multiple passes to build up thicker coatings or repair worn surfaces.Key FeaturesLow Dilution: The mixing of base material into the clad layer is minimal (
