| Key components such as runners, buckets, and blades in large hydropower equipment are crucial for the stable and efficient operation of hydropower units. To meet performance requirements of these components under extreme conditions, the application of high-performance manufacturing technologies is essential. In recent years, advancements in forging, welding and additive manufacturing, laser cladding, and spraying technologies have yielded significant results in key components of hydropower equipment. This paper summarized the current status of high-performance manufacturing technologies for key components of large hydropower equipment, focusing on the application of forging, welding and additive manufacturing, laser cladding, and spraying in critical components like runners, buckets, and blades. By systematically discussing forging process parameters, welding residual stress, and the surface strengthening effects of laser cladding and spraying on key components of hydropower equipment, the advantages and challenges of these technology processes in enhancing component performance were analyzed. The forging process could significantly enhance the mechanical properties and microstructure of materials, improving fatigue resistance and impact toughness of components. Welding and additive manufacturing processes reduced residual stress and deformation, improving joining quality of components. Laser cladding and spraying technologies enhanced surface wear, corrosion, and oxidation resistance, thereby extending service life. Additionally, this paper identified current research deficiencies in manufacturing key components of large hydropower equipment and suggested future research priorities of relevant fields. |
