Nano coatings have a wide range of applications, especially in the application of hot end components of aircraft engines and gas turbines (two engines). Because the two-engine equipment is not only an important symbol of a country's science, technology, industry, and economy, it is known as the treasure of the country and the "crown jewel" of modern industry, and the two-engine equipment occupies an important strategic position in our country's national defense construction. Experts predict that in the next 10 years, the scale of my country's aviation market will exceed one trillion yuan. Therefore, our country has a more urgent demand for two-engine equipment and its key materials, including coating materials.
