Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a spraying method for aviation materials. Background technique [0002] In the process of aviation manufacturing development, the replacement of materials presents a high-speed change, and materials and aircraft have been constantly developing under the mutual promotion. "One generation of materials, one generation of aircraft" is a true portrayal of the history of world aviation development. The special working environment of aviation products places light weight, high strength, high temperature and corrosion resistance on the performance requirements of materials. The light-weight and high-strength means that the material is required not only to have high strength but also to have low density. High temperature corrosion resistance High temperature means that the material can withstand higher working temperature, and corrosion resistance means that the material h...
