[0003] Traditional corrosion resistance detection devices for nano-deposited coatings generally use the method of directly spraying corrosive liquids on the surface of the nano-deposited coating to simulate the actual corrosion environment, and then evaluate the corrosion resistance of the coating; however, when the corrosive liquid is sprayed onto the surface of the nano-deposited coating, it is difficult to quickly and completely remove the corrosive liquid from the coating surface, and a certain amount of residual liquid will remain on the surface of the nano-deposited coating; these residual liquids cause serious interference to the image acquisition process of the linear array camera in the subsequent detection link; specifically, the residual liquid will form irregular liquid films or droplets on the coating surface, resulting in abnormal optical phenomena such as scattering and refraction of light on the coating surface, making the images collected by the linear array camera appear blurred, distorted, color deviation and other problems, thus seriously affecting the accuracy and reliability of the evaluation of the corrosion resistance of the nano-deposited coating.
