Literature review demonstrates enhanced hardness and wear resistance in high-temperature alloy coatings, highlighting significant durability gains for critical industrial components.
Laser cladding, an advanced surface modification technology, is characterized by low dilution rates, dense coating layers, strong coating‐substrate adhesion, and environmental sustainability. High‐temperature alloys demonstrate exceptional thermal resilience and corrosion resistance, making them indispensable for critical components in aviation, energy, and chemical industries. The application of laser cladding can significantly enhance the surface properties of high‐temperature alloys, improving hardness and wear resistance while extending service life. Furthermore, this technology enables precise control over coating microstructures through grain size refinement and phase composition optimization, thereby enhancing mechanical properties and durability. Consequently, laser cladding demonstrates considerable potential for surface modification of high‐temperature alloys, offering robust solutions for material property enhancement and industrial demands. This review systematically examines the effects of laser cladding on the microstructure and surface properties of high‐temperature alloy coatings, while discussing future development trends and application prospects.
