Accordingly, researchers have been working on corrosion-resistant metals and coating the surfaces of the metals with a corrosion-resistant protective film to improve the corrosion resistance of the metals.
In the above-mentioned studies, it is inevitable to relate to a method for detecting corrosion resistance of metals. The currently commonly used method for detecting the corrosion resistance of the metal is as follows: firstly, spraying 5% saline on the surface of a metal test piece by using a sprayer, and then periodically observing the corrosion condition of the surface of the metal test piece to determine the corrosion resistance of the metal to be tested.
