Nine methods of metal surface treatment process
Release Date:2022-05-31

To enhanceMetal Surface ProcessThe appearance, texture, function and other aspects of the performance of the product usually require the treatment of the metal surface, the so-called surface treatment is the physical or chemical methods to form the surface of the material with some special characteristics of the surface layer.

1.Anodizing

Using the electrochemical principle, an aluminum oxide film is generated on the surface of aluminum and aluminum alloys. The main functions of this oxide film are protection, decoration, insulation, and wear resistance. Different processes are used for single color, gradient color and dual color anodizing, and the main considerations are the amount of oxidizer, suitable temperature and current density in order to improve the oxidation yield.

2.Electrophoresis

The role of electrophoresis is to maintain the luster of the metal surface in addition to enhancing the surface properties with a high degree of corrosion resistance. Its way is to realize various colors on the surface of products for materials such as stainless steel and aluminum alloy. The electrophoresis process is relatively simple, mainly through the pretreatment of-Electrophoresis-Three steps to drying.

3.Micro-arc oxidation

The process of using electrolyte solution to generate a vitrified surface layer using high voltage electricity, the micro-arc oxidation process is the most expensive due to high electricity consumption, and only two colors, black and gray, can be achieved.

4.PVD Vacuum Plating

PVD can realize the metal surface plating high hardness, high wear resistance metal ceramic decorative coating, PVD vacuum plating process means to use the logistics process to deposit thin film technology.

5.Electroplating

By plating products can make the coating glossy, high-quality metal appearance, plating process means through the electrolytic effect of the metal surface attached to the metal film so as to play the role of corrosion, can improve wear resistance, electrical conductivity, reflectivity, aesthetics, etc.

6.Powder Coating

Powder coating is commonly used in the appearance of architectural furniture products and heat sinks, powder coating process above pieces-Electrostatic precipitation-Spraying-Low temperature leveling-Baking five steps, mainly through the powder spraying equipment to powder coating to the surface of the workpiece,The electrostatic action makes it adsorbed on the surface of the workpiece, forming a powder-like coating, which is baked at high temperature to form a different effect.

7.Brushed metal

The treatment of brushing is a means to produce a non-mirrored metallic luster on the metal surface also eliminating minor imperfections, mainly by forming a line pattern on the surface of the workpiece by grinding the product to provide a decorative effect.

8.Polishing

In order to improve the dimensional accuracy and geometric progress of the workpiece, polishing can make the surface of the product smooth and mirror shine, the way of the process is to use flexible polishing tools and abrasive particles and other polishing media to finish the surface.

9.Etching

Through the plate exposure, after the development, the protective film of the area to be moment removed, the etching of the metal in contact with the chemical solution, the use of two positive graphics through the chemical flooding from both sides of the grinding to achieve the effect of dissolution corrosion, the formation of embossing or hollow molding effect. There are two ways to achieve the process, namely: exposure method, screen printing method.
