Laser cladding is an advanced surface engineering technology that deposits high-performance metallic materials onto the surface of a substrate through a precisely controlled laser heat source, producing a dense metallurgically bonded coating with excellent wear resistance, corrosion resistance, oxidation resistance, and mechanical strength.

Today, laser cladding has become an important manufacturing and remanufacturing technology for civil aviation, energy equipment, industrial rotating machinery, precision manufacturing, transportation, and heavy industry. By restoring worn components and improving surface performance, laser cladding extends equipment service life, reduces maintenance costs, and improves long-term operational reliability.

Compared with conventional welding, electroplating, or thermal spraying, laser cladding provides localized heat input, low dilution, excellent dimensional control, and superior metallurgical bonding, making it particularly suitable for repairing and strengthening high-value precision components.
