What are the advantages of Dalian blackening surface treatment

Dalian blackening surface treatment is a very common surface treatment method for metal materials. It forms a dense oxide film on the metal surface through chemical reactions and physical processing methods, improving its anti-corrosion, wear resistance, fatigue resistance, and other properties, while enhancing its aesthetic and decorative properties. Blackening surface treatment has a wide range of applications in the fields of aviation, automotive, electronic products, and is an important part of metal material surface treatment.

In the field of architecture, blackened surface treatment is often applied in the preservation of cultural heritage and architectural decoration. It can change the color and texture of the metal surface, reduce reflection, and make the appearance more elegant and beautiful. In addition, blackening surface treatment can also reduce the cost of building materials and improve their overall economic benefits.

What are the advantages of Dalian blackening surface treatment

(1) Increase the corrosion resistance of materials: After the formation of a black oxide layer on the surface of some materials, a closed protective layer will be formed on the surface of the material, reducing exposure to external environments such as air and water, thereby reducing the corrosion damage of the material.

(2) Increase the wear resistance of the material: Blackening surface treatment can form a harder oxide layer on the material surface, thereby increasing the wear resistance of the material.

(3) Improving the aesthetics of the material: After blackening surface treatment, a black oxide layer is formed on the surface of the material, which is visually very beautiful.

The basic principle of blackening surface treatment is to expose the metal surface to a solution containing an oxidant, causing the oxidant to form a chemical reaction with the metal surface, thereby generating a layer of black or dark gray oxide film. This type of oxide film can play a role in corrosion prevention, oxidation prevention, etc., while also improving the hardness and aesthetics of the metal.

Blackening surface treatment can optimize the surface performance of metal materials and improve their mechanical properties such as corrosion resistance, wear resistance and contact resistance. Because the surface is oxidized, the surface facial mask is protected. The blackening of metal surfaces is often caused by the action of organic, inorganic acid agents, electrolytes, and other liquids, which cause chemical reactions on the metal surface, forming a uniform and dense metal oxide film. The oxide layer can improve the corrosion resistance of metal materials, enhance their mechanical properties, and form a dense oxide film on the surface of metal objects, improving their wear resistance and electrical resistance.
