Description

Technical Field

[0001] The utility model belongs to the technical field of anodizing, and in particular relates to a local sulfuric acid anodizing device for parts. Background Art

[0002] Anodizing is an electrochemical treatment technology that immerses metal materials in an electrolyte to make them anodes and passes an electric current through them, thereby forming an oxide film on the metal surface. This oxide film has excellent corrosion resistance, wear resistance, insulation and decorative properties, and can also enhance the strength and hardness of the material. Therefore, anodizing is widely used in the surface treatment and processing of various metal materials, such as aluminum, magnesium, zinc, titanium, etc.

[0003] In many production processes, only specific parts of a part need to be oxidized. If the entire part is anodized with sulfuric acid, it may cause unnecessary waste because some parts may not need to be oxidized. In addition, local oxidation can reduce processing time and energy consumption, thereby reducing production costs. Local sulfuric acid anodizing can reduce the use of chemicals and the generation of wastewater, thereby reducing the impact on the environment.

[0004] Therefore, in view of the above situation, it is urgent to develop a local sulfuric acid anodizing device for parts to overcome the shortcomings in current practical applications. Utility Model Content
