Note

Among various oxide films, the sulfuric acid oxide film is an important factor affecting the high purity and transparency of the aluminum alloy oxide film, including the oxide film thickness of the sulfuric acid oxide film, the oxide film porosity, the oxide film purity, and the sealing quality. Mirror effect.

If the oxide film contains too much impurity ions such as silicon, manganese, iron, copper, chromium, etc., the purity of the platinum-rhodium thermocouple oxide film is low, the transparency is lowered, and the mirror treatment effect of the aluminum casting is greatly reduced. This is because although the oxide film is light-transmissive, there is some light scattering loss, and the transparency is also decreased when the thickness of the oxide film is increased.

The impurities in the oxide film of the aluminum casting are mainly derived from the aluminum member itself, and the secondary source is the oxidation bath. Therefore, the content of alloying elements in the aluminum part is appropriately reduced, the impurity content of the aluminum part is minimized, and even the high-purity aluminum can improve the purity of the oxide film. At the same time, it is necessary to reduce the impurity ions in the bath, and keeping the bath fresh can also improve the purity of the oxide film.

Therefore, in order to obtain an aluminum casting with perfect oxidized mirror effect, it is necessary to improve the transparency of the oxide film, and to start from the four aspects of controlling the thickness of the oxide film, reducing the porosity of the oxide film, improving the purity of the oxide film, and ensuring proper sealing. The change in the mirror effect of aluminum castings.
