Micro arc oxidation (MAO): Micro-arc oxidation (MAO) is also called plasma electrolytic oxidation. MAO can create an oxide coating on conductive materials such as metallic materials. "Metallic material" means pure metal, metal alloy, intermetallic compound (intermetallic) or metal-containing composite, etc. Metal materials may include aluminum, magnesium, titanium, etc. MAO uses a high electromotive force so that a discharge can occur and the resulting plasma can cause structural modification of the oxide layer.

MAO creates tiny discharges on the surface of metallic materials immersed in electrolyte. MAO treatment can be used to form relatively thick and mostly crystalline oxide coatings. The thickness of the coating may be, for example, tens or hundreds of microns, but is not limited to any specific value. For example, MAO coatings can be produced with larger or smaller thicknesses depending on the application and process requirements. The resulting micro-arc oxide coating may be dense and/or ductile and may have a relatively high hardness, particularly as opposed to an oxide layer formed by anodization.

In contrast to deposition processes, MAO is a chemical conversion technology. The oxide layer formed as a result of MAO is the result of oxidation of the underlying metallic material object, rather than an oxide layer being deposited on the object. Compared with deposition-based processes (such as spraying processes), MAO coatings can have higher adhesion to underlying metal material objects.

Formation treatment: Chemical conversion treatment is to chemically or electrochemically treat the metal surface to obtain a coating of metal compounds, which has improved corrosion resistance, paint bonding, metal coloring, and chemical Grinding (chemical polishing) and other functions. There are many types of chemical treatment, such as chromate treatment, phosphate treatment, non-chromium treatment, metal coloring, chemical grinding, etc. Chemical formation treatment has the characteristics of good corrosion resistance, good adsorption, good electrical insulation, and non-adhesion of molten metal. Commonly used as chemical treatment agents for steel, aluminum, zinc, stainless steel, copper, magnesium, etc.

CNC highlight processing: Computer Numerical Control (CNC) uses NC program instructions to be input into the memory of the CNC system, then compiled and calculated by the computer, and the information is transmitted to the driver through the displacement control system to drive the motor to cut the designed parts. . Usually, a work machine (machine tool) controlled by a computer is commonly called CNC. For example, diamond tool processing is a super-precision turning technology that uses sharp natural diamond tools to process soft metals such as aluminum alloys and copper alloys to obtain optical mirror surfaces. Using diamond tools to process optical metal mirrors can achieve higher reflectivity. Coupled with the emergence of computer numerical control (CNC) super-precision lathes in recent years, the contour processing of aspheric mirrors has been better solved. In addition, after the tool cuts the metal surface, it achieves a high gloss effect and presents a metallic texture.

With the development of high-performance, high-precision CNC machine tools and excellent-performance diamond tools, CNC high-gloss processing technology has made great breakthroughs, and milling (turning) instead of grinding has become a mature application. The principle of CNC high-gloss processing is to use diamond high-gloss tools on precision CNC machining equipment, combined with scientific and reasonable cutting parameters and processes, to achieve a sparkling processing surface effect. CNC high-gloss processing materials can be acrylic, plexiglass, copper alloy, copper parts, aluminum alloys, aluminum materials, copper parts, magnesium alloys, zinc alloys, etc.

Electrophoretic coating (electro-coating; ED): Electrophoretic coating (electro-coating) is a coating method that uses an external electric field to deposit pigments suspended in an electrophoretic fluid on the surface of magnesium alloy objects. Electrophoretic coating is water-soluble, non-toxic, and easy to control automatically. It has been widely used in automobiles, building materials, hardware, home appliances and other industries. The principle of electrophoretic coating is that the resin contained in the cathodic electrophoretic coating has a basic group, which becomes a salt after being neutralized by acid and is soluble in water. After direct current is passed, the acid anions move toward the anode, and the resin ions and the pigment particles wrapped in them move toward the cathode with positive charges and are deposited on the cathode. This is the basic principle of electrophoretic coating (commonly known as plating). Electrophoretic coating is a very complex electrochemical reaction. It is generally believed that at least four effects, namely electrophoresis, electrodeposition, electrolysis and electroosmosis, occur simultaneously.

Characteristics of electrophoretic surface treatment technology: Electrophoretic paint film has the advantages of full, uniform, flat and smooth coating. The hardness, adhesion, corrosion resistance, impact performance and penetration performance of electrophoretic paint film are significantly better than other coating processes.

UV (ultraviolet) paint: UV paint is ultraviolet light curing paint. UV paint generally refers to light-curing paint (photosensitive paint), which uses ultraviolet light as the energy source for curing paint, also known as UV-cured paint. No heating is required and it can be quickly cured to form a film on flammable substrates such as paper, plastic, leather and wood. It is mainly composed of photosensitive resin, photosensitizer (photoinitiator) and diluent. At the same time, some additives are added, such as heat stabilizer, and pigments and fillers are added when preparing colored paint. Photosensitive resins are generally low molecular weight resins with unsaturated bonds, such as unsaturated polyesters and acrylic oligomers; photosensitizers are compounds that easily absorb ultraviolet light and generate active free radicals, such as benzophenone and benzoin alkyl ethers. Class; the main function of the diluent is to reduce the viscosity of the paint, and also participates in the curing film formation, that is, the reactive diluent, such as styrene, acrylate, etc. The advantages of light-curing coatings are short curing time (a fraction of a second to a few minutes), low curing temperature, and low volatile content. It is a new type of coating that saves energy, saves resources, is pollution-free, and is highly efficient.
