What are the three main methods for blackening surface treatment in Dalian

release date:2023-04-10 author: Click:

Dalian blackening surface treatment is a method of treating the surfaces of materials such as metals, ceramics, and plastics into black oxides. Acid washing, heat treatment, and chemical reaction methods are common methods for treating blackened surfaces. After blackening surface treatment, the material surface has advantages such as corrosion resistance, wear resistance, and aesthetics, and has been widely used in various industrial fields.


Blackening surface treatment has a wide range of applications in various fields. In the industrial field, blackening surface treatment can greatly improve the physical properties of metal materials, such as corrosion resistance, oxidation resistance, contact heat resistance, etc. This treatment method is often combined with other treatment methods (such as polishing or electroplating) to achieve better results.


There are three main methods for blackening surface treatment in Dalian:


Heat treatment method: Burn the metal surface red and soak it in a solution containing oxidants such as copper nitrate to react with the oxidant, forming an oxide film. This method is applicable to metals such as copper and aluminum.


Chemical oxidation method: Soak the metal surface in an alkaline or neutral solution containing an oxidant to react with the oxidant and form an oxide film. This method is applicable to metals such as iron, steel, and stainless steel.


Electrochemical oxidation method: The metal surface is used as an anode and placed in an electrolyte containing an oxidant. A certain voltage and current are applied to react with the oxidant, forming an oxide film. This method is applicable to metals such as aluminum and magnesium.


Blackening surface treatment is essentially an oxidation reaction. By forming a black oxide layer on the metal surface, the physical and chemical properties of the metal surface are altered. The thickness and properties of the oxide layer are related to factors such as treatment solution formula, treatment temperature, and time, while the depth and color estimation of surface treatment are the main factors affecting the blackening effect. Due to its compactness, the black oxide layer can greatly improve the corrosion resistance, wear resistance, and strength of metal materials. Blackening surface treatment is often combined with other surface treatment methods (such as electroplating, spraying, etc.) to achieve better results.


Blackening surface treatment has been widely used in various fields such as aerospace, automotive manufacturing, and architectural decoration. The material surface treated with blackening not only has characteristics such as corrosion resistance and wear resistance, but also greatly improves its aesthetics. For example, black anti-corrosion treatment not only protects steel materials from oxidation damage, but also enables them to have better visual effects in the field of industrial design.
