Black electroplating is a surface treatment technology that can form a uniform black coating on the metal surface, improving the corrosion resistance and aesthetics of the metal surface.
I. Black electroplating production method
Black electroplating is a surface treatment technology that forms a uniform black coating on the metal surface. The production method of black electroplating is generally divided into the following steps:
1. Pretreatment: Clean, degrease, remove oxide skin and other treatments on the metal surface to facilitate the adhesion of subsequent electroplating coating.
2. Electroplating base layer: Immerse the metal part in the electroplating solution and form a layer of plating on the metal surface through electrolytic reaction. The base layer usually uses a nickel layer or a copper layer to improve the adhesion of the coating.
3. Black electroplating: On the basis of the base layer, immerse the metal part in the electroplating solution containing dyes to form a black coating on the metal surface through electrolytic reaction. Black electroplating generally uses chemical oxidation or phosphate methods.
4. Post-treatment: Clean, neutralize, rinse and other treatments on the electroplated parts to facilitate the curing and subsequent use of the coating.
II. Application fields of black electroplating
Black electroplating has the advantages of beauty, corrosion resistance, and wear resistance, and is widely used in automobile, machinery, electronics, furniture and other industries. Specific application fields include:
1. Automobile industry: Black electroplating can be used on automobile exterior parts, wheels, exhaust pipes and other parts to improve the beauty and corrosion resistance of automobiles.
2. Machinery industry: Black electroplating can be used for surface treatment of mechanical parts, tools, knives, etc. to improve their wear resistance and beauty.
3. Electronics industry: Black electroplating can be used for surface treatment of electronic products such as mobile phones, tablets, and laptops to improve their beauty and corrosion resistance.
4. Furniture industry: Black electroplating can be used for surface treatment of furniture hardware, door handles, faucets, etc. to improve their beauty and corrosion resistance.
In short, as a surface treatment technology, black electroplating can provide metal products with advantages such as beauty, corrosion resistance, and wear resistance, and has broad application prospects.
