Characteristics Of Anodizing Treatment On Surface Of Zinc Alloy Knob

Pulished on Feb. 20, 2019

(1) High hardness. The hardness of the pure aluminum oxide film of Zinc Alloy Knob is higher than that of the aluminum alloy oxide film. Generally, its hardness is related to the alloy composition of aluminum and the technical conditions of the electrolyte during anodization. The anodized film is not only high in hardness but also has good wear resistance. In particular, the oxide film having a porous surface layer has the ability to adsorb a lubricant, and can further improve the wear resistance of the surface.

(2) Custom Electric Oven Cooker Knob has high corrosion resistance. This is due to the high chemical stability of the anodized film. The anodized film of pure aluminum has been tested to have better corrosion resistance than the anodized film of aluminum alloy. This is because the inclusion of the alloy component or the formation of the metal compound cannot be oxidized or dissolved, and the oxide film is discontinuous or voids are generated, so that the corrosion resistance of the oxide film is greatly lowered. Therefore, the film obtained by anodizing generally must be subjected to a sealing treatment to improve its corrosion resistance.

(3) It has strong adsorption capacity. The anodized film of aluminum and aluminum alloy has a porous structure and has strong adsorption capacity. Therefore, filling the holes with various pigments, lubricants, resins, etc. can further improve the protection, insulation, wear resistance and decorative properties of the aluminum products.

(4) has good insulation properties. The anodized film of aluminum and aluminum alloys does not have the conductive properties of metals, and becomes a good insulating material.
