Features of PVD coating machines: Films coated using PVD coating technology have high hardness, high wear resistance, good corrosion resistance and chemical stability, and a longer lifespan. At the same time, the film layer can greatly improve the appearance and decorative performance of the workpiece. The types of film layers that can be electroplated through PVD coating, PVD coating technology is an environmentally friendly surface treatment method that can obtain micrometer-level coatings.

　　PVD coating technology can be divided into three categories: vacuum evaporation coating, vacuum sputtering coating, and vacuum ion plating. Corresponding to the three major categories of PVD technology, the corresponding vacuum coating equipment includes vacuum evaporation coating machines, vacuum sputtering coating machines, and vacuum ion plating machines. In the past decade, vacuum ion plating technology has developed rapidly and has become one of the advanced surface treatment methods. What we usually refer to as PVD coating is vacuum ion plating; PVD coating machine Usually refers to a vacuum ion coating machine.

　　The specific principle of PVD coating technology is that under vacuum conditions, low-voltage, high-current arc discharge technology is used to evaporate the target material through gas discharge. The evaporated material and gas are ionized, and the evaporated material and its reaction products are deposited on the workpiece through the acceleration of the electric field.

　　 PVD coating machine Features. Films coated with PVD coating technology have high hardness, high wear resistance, good corrosion resistance and chemical stability, and a longer service life; at the same time, the film layer can greatly improve the appearance and decorative performance of the workpiece. Types of film layers that can be electroplated through PVD coating, PVD coating technology is an environmentally friendly surface treatment method that can obtain micrometer-level coatings. Various single metal films, nitride films, carbide films, and oxide films can be prepared. The PVD coating machine has a micrometer-level and thin coating thickness, generally 0.3 to 5 micrometers, of which the decorative coating thickness is generally 0.3 to 1 micrometer, so it can improve various physical and chemical properties of the workpiece surface without affecting the original size of the workpiece, and no further processing is required after plating.

　　Types of colors that can be plated with PVD coatings—Currently, PVD coatings can produce colors such as dark gold, light gold, brown, bronze, gray, black, dark gray, and seven colors. By controlling the relevant parameters during the coating process, the color of the coating can be controlled. After PVD coating, relevant instruments can be used to measure the color, thereby quantifying the color to determine whether the color after plating meets the requirements.

　　Similarities and differences between PVD coating and traditional chemical plating. The similarity between PVD coating and traditional chemical plating is that both belong to the category of surface treatment, where one material covers the surface of another material in some way. The difference is that the coating of the pvd coating machine has stronger bonding strength with the workpiece surface, higher hardness, better wear resistance and corrosion resistance, and more stable coating performance; PVD coatings do not produce toxic or polluting substances.

　　Currently, PVD coating machine Coating technology is mainly used in industrial fields. The application of pvd coating machine coating technology can be divided into two categories: decorative coating and tool coating. The main purpose of decorative electroplating is to improve the appearance, decorative performance, and color of the workpiece, while making the workpiece wear-resistant and corrosion-resistant, and extending its service life. This is mainly used in various fields of the hardware industry, such as door and window hardware, locks, bathroom hardware, etc. The main purpose of tool electroplating is to improve the surface hardness and wear resistance of the workpiece, reduce the surface friction coefficient, and extend the service life of the workpiece. This is mainly used for various knives and scissors, cutting tools, various hardware tools, various molds, and other products.
