In the vast galaxy of modern industry, thermal spraying technology is like a brilliant star, shining with its unique charm in multiple fields and becoming an indispensable behind the scenes force driving industrial progress

Thermal spraying technology plays a key role in the aerospace industry. Aircraft engines are the heart of airplanes, and their key components such as blades need to withstand extreme working conditions of high temperature, high pressure, and high-speed rotation. By using thermal spraying technology to prepare ceramic coatings on the surfaces of these components, the blade temperature can be effectively reduced, and their oxidation and corrosion resistance can be improved, thereby extending the service life of the engine and enhancing the reliability and economy of the aircraft. In the aerospace field, thermal spraying coats the high-temperature components of rocket engines with protective coatings to resist the erosion of hot gases and ensure the smooth progress of space missions

The mechanical manufacturing industry also relies on the assistance of thermal spraying. The core components of large machine tools, mining machinery, and other equipment, such as spindles and hydraulic cylinders, are prone to wear and corrosion when exposed to high-intensity working environments for a long time. Thermal spraying technology sprays wear-resistant and corrosion-resistant coatings on its surface, significantly improving the service life of components and the overall performance of equipment. In automobile manufacturing, components such as engine cylinder blocks and piston rings are coated with thermal spraying to enhance their wear resistance, reduce fuel consumption and exhaust emissions, and contribute to the green development of the automotive industry

In the field of energy and power, thermal spraying technology is a solid backing to ensure the stable operation of equipment. In thermal power generation, the wear and tear of components such as ball mills and turbine rotors have always plagued production efficiency. The application of thermal spray wear-resistant coating effectively solves this problem and improves the reliability and availability of power generation equipment. The overcurrent components of hydropower equipment, such as turbine blades, are protected against water flow erosion and cavitation damage through thermal spraying and wear-resistant coatings, ensuring the long-term stable power generation of hydropower stations The industrial chain driving effect of thermal spraying technology is significant. The upstream spraying material industry, such as metal powder, ceramic powder, etc., continues to grow with the development of thermal spraying technology. The research and production of new spray coating materials not only meet the growing market demand, but also promote the progress of materials science. Downstream industries such as mechanical manufacturing, aerospace, energy and power have benefited greatly from the application of thermal spraying technology, resulting in significant improvements in product performance and market competitiveness The advantage of thermal spraying technology lies in its wide adaptability to the substrate material. Whether it is metal, alloy or composite material, they can all become a stage for the application of thermal spraying technology. The flexible control of coating thickness enables it to meet the requirements of ultra-thin functional coatings and achieve structural coatings several millimeters thick. The flexibility of the process is particularly commendable, as it can be used for initial manufacturing surface strengthening of components, as well as rapid repair after component damage, greatly reducing the cost and resource consumption of industrial production

With the continuous advancement of technology, thermal spraying technology is also constantly innovating. The emergence of new spray coating materials such as nanostructured coating materials has achieved a qualitative leap in coating performance. The popularization of automated and intelligent spraying equipment has improved the uniformity and stability of coating quality, further enhancing production efficiency

In the future, thermal spraying technology will expand in more emerging fields. In the biomedical field, surface modification of artificial joints is expected to use thermal spraying technology to safeguard human health. In the surface treatment of batteries and motor components in new energy vehicles, thermal spraying technology will also help realize the dream of green travel and continue to write a legendary chapter in industrial surface treatment
