Long-term service of aerospace vehicles in complex (high altitude, high speed, rapid changes) and harsh (high temperature, high humidity, heavy load, ocean salt spray, acid rain, etc.) harsh environments often cause abrasions on the surface of aviation equipment and loss of coatings. Luster, cracks and falls off, and loses its protective effect; metals undergo oxygen-absorbing corrosion, electrochemical corrosion, etc., which lead to the destruction of aviation materials, which directly affects the normal operation of the parts. The surface of aerospace parts not only needs to have a better coating but also the corroded parts need to be cleaned and repaired.
