As an advanced surface engineering and remanufacturing method, laser cladding\u00a0technology uses a high-energy laser beam to rapidly melt pre-deposited or synchronously delivered alloy powders, forming a metallurgically bonded cladding layer on the substrate surface. This significantly enhances the wear resistance, corrosion resistance, and high-temperature performance of the workpiece.
