Since many components made of metal materials are often exposed to a particular environment, for example, in coastal areas, the metal components are often exposed to moisture, and therefore, the corrosion resistance of the metal components is highly required. The most common anticorrosion treatment is to add an anticorrosion coating layer, such as a zinc coating layer, a zinc-aluminum alloy coating layer, etc., on the surface of the metal member, so that the amount of the coating layer is required to be detected, and is generally expressed by the coating weight (g/m 2). The main method for detecting the weight of the coating at present is an acid etching method: the method comprises the following steps of putting a sample into an acid etching solution, taking out the sample when hydrogen evolution obviously stops, and calculating the coating weight of the sample through the weight difference of the sample before and after a test and the surface area of a coating.
