In the field of automotive parts, the manifold is one of the key components connecting the engine and the exhaust system, and its role is to guide the flow of emissions, reduce noise, and improve engine performance. With the increasing quality and performance requirements of auto parts, the relevant consumer groups have higher and higher requirements for the manifold, which not only needs to have good high temperature resistance and corrosion resistance, but also has sufficient strength and durability. Therefore, among many manifold treatment technologies, ceramic coating surface treatment is the best choice with significant advantages in all aspects, and it is more and more widely used in manifold treatment. In this paper, the production process and technology of ceramic coating surface treatment for manifold will be introduced in detail, in order to provide meaningful reference for auto parts modification enthusiasts.
