Application of Thermal Spraying Technology in Gas Turbine Maintenance

Gas turbine power generation is becoming a hot topic in China's power industry. Addressing the issue of China's reliance on others for heavy-duty gas turbines is both a national imperative and the shared dream of all Chinese power professionals. For a long time, developed Western countries have strictly controlled the export of high-tech products to China, and high-power gas turbine technology has undoubtedly been a key focus of their protection efforts—whether it’s the installation of new units, the maintenance of older ones, or the manufacturing and repair technologies for critical components.
