Problems solved by technology

[0003] With the rapid development of industries such as aviation, aerospace, automobiles and weapons, the requirements for the performance of metal materials are getting higher and higher. Not only are metal materials required to work normally at higher temperatures and harsher corrosion environments, but also It is difficult for organic polymer materials to meet the current use requirements if metal materials have good performances such as anti-vibration, anti-fatigue, anti-temperature sudden change and anti-scouring.

Ordinary coatings generally cannot form a dense protective layer through self-reaction at a certain temperature, and it is also impossible to react with metal materials in a short period of time to form a metal complex layer, thereby producing good adhesion; When used at the above temperature, the traditional coatings are somewhat insufficient in terms of heat and humidity resistance, salt spray resistance and high and low temperature performance.
