1. Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is the use of polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece. Polishing cannot improve the dimensional accuracy or geometric accuracy of the workpiece, but aims to obtain a smooth surface or mirror gloss, and is sometimes used to eliminate gloss (matting).2. Sandblasting uses the impact of high-speed sand flow to clean and roughen the surface of the substrate. Compressed air is used as power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, emery sand, iron sand, Hainan sand) at high speed to the surface of the workpiece to be treated, so that the appearance or shape of the outer surface of the workpiece surface is changed , Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved. Therefore, the fatigue resistance of the workpiece is improved, and it and the coating are increased. The adhesion between the layers extends the durability of the coating film, and is also conducive to the leveling and decoration of the coating.3. Wire drawing is a surface treatment method that forms lines on the surface of the workpiece by grinding the product to achieve a decorative effect. According to the different lines after drawing, it can be divided into: straight line drawing, random line drawing, corrugation, and swirling. Surface wire drawing is a surface treatment method that forms lines on the surface of the workpiece by grinding products to achieve a decorative effect. Because the surface drawing process can reflect the texture of metal materials, it has been favored by more and more users and more and more widely used.4. Anodizing An electrolytic oxidation process in which the surface of aluminum and aluminum alloys is usually transformed into an oxide film, which has protective, decorative, and other functional properties. Anodizing of aluminum starting from this definition includes only the part of the process of forming anodized film. A metal or alloy product is used as an anode, and an oxide film is formed on the surface by electrolysis.5. The electrophoresis process is divided into anode electrophoresis and cathodic electrophoresis. If the coating particles are negatively charged, the workpiece is the anode, and the coating particles are deposited on the workpiece to form a film under the action of the electric field force is called anodic electrophoresis; on the contrary, if the coating particles are positively charged, the workpiece is the cathode, and the coating particles are deposited on the workpiece to form a film. Cathodic electrophoresis.6. PVD is the abbreviation of English Physical Vapor Deposition (Physical Vapor Deposition), which refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions, the use of gas discharge to evaporate the target material and make the vaporized substance and gas occur Ionization uses the acceleration of an electric field to deposit the evaporated substance and its reaction products on the workpiece. The physical vapor deposition technology has a simple process, improves the environment, has no pollution, less consumables, uniform and dense film formation, and strong bonding with the substrate. This technology is widely used in aerospace, electronics, optics, machinery, construction, light industry, metallurgy, materials and other fields. It can be prepared with wear resistance, corrosion resistance, decoration, conductivity, insulation, light guide, piezoelectric, magnetic, lubricating, Superconducting and other characteristics of the film.7. Electroplating (Electroplating) is the process of plating a thin layer of other metals or alloys on the surface of some metals using the principle of electrolysis. It is the process of using electrolysis to attach a layer of metal film to the surface of the metal or other materials. To prevent satinless steel metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance beauty. The outer layer of many coins is also electroplated.8. Etching usually refers to etching, also known as photochemical etching, which refers to the removal of the protective film of the area to be etched after exposure to plate making and development, and contact with chemical solutions during etching to achieve the effect of dissolving and corroding, forming unevenness or hollowing out.
