The most commonly used method is the protective coating method, which is to coat a layer of Si, Al, Sn and other metal oxide inorganic materials on the surface of the substrate to prevent the corrosion of the substrate by AO
The most commonly used protective coating method is to coat the surface of the substation with a layer of Si, Al, Sn and other metal oxide inorganic materials to prevent AO from eroding the substation.
