When the particle diameter of the crystalline oxide is small, diffuse reflection of light is mainly generated, and as time goes up, the thickness of the oxide film increases, so that the reflection of light decreases, and when the thickness exceeds 40nm, a dark blackening defect is visually shown.
The patent (CN 110004389A) discloses an anti-blackening zinc-aluminum-magnesium coated steel and a preparation method thereof, and a zinc-magnesium-containing hydroxide film and/or a zinc-magnesium-containing basic carbonate film are/is obtained by controlling a series of process parameters such as magnesium-aluminum element content, surface roughness, oxide film thickness, specific steel base temperature and the like in a coating, so that the technical effect that the steel surface of the zinc-aluminum-magnesium coated steel is extremely difficult to darken and blacken in a complex atmospheric environment is achieved.

However, the method requires that the alloy elements are added into the hot-dip galvanized alloy, so that the alloy elements are easy to burn at high temperature, and the production safety risk is high.
