The PVD technology of pvd coating machine can be applied to the processing and manufacturing of marine supplies, jewelry, handicrafts, door and window hardware, kitchen and bathroom hardware, lamps, marine supplies, jewelry, handicrafts, and other decorative products. The application is very extensive. Many customers are also very interested in the relevant knowledge when purchasing equipment. Today, we have gathered into a small vacuum knitting to introduce the general knowledge of PVD coating of vacuum coating machine, I hope it can help you improve your knowledge and skills.

The specific principle of PVD coating (ion coating) technology is to use low voltage and high current arc discharge technology under vacuum conditions, use gas discharge to evaporate the target and ionize the evaporated substance and gas, and use the acceleration of electric field to deposit the evaporated substance and its reaction products on the workpiece.
The characteristics of PVD coating film. The film coated by PVD coating technology has the characteristics of high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability. The service life of the film is longer; At the same time, the film can greatly improve the appearance and decoration performance of the workpiece.
PVD coating technology is an environment-friendly surface treatment method that can truly obtain micron level coating and has no pollution. It can prepare various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (TiN, ZrN, CrN, TiAlN), carbide films (TiC, TiCN), and oxide films (such as TiO, etc.). Thickness of PVD coating film - the thickness of PVD coating film is micron, which is relatively thin, generally 0.3 μ m～5 μ m. The thickness of decorative coating is generally 0.3 μ m～1 μ m. Therefore, various physical and chemical properties of the workpiece surface can be improved without affecting the original size of the workpiece. No further processing is required after plating.
Color types of films that can be plated by PVD coating - PVD coating can currently make dark golden yellow, light golden yellow, coffee, bronze, gray, black, gray black, seven colors, etc. The color can be controlled by controlling the relevant parameters in the coating process; After coating, relevant instruments can be used to measure the color, so that the color can be quantified to determine whether the color plated meets the requirements.
PVD coating technology of pvd coating machine is currently mainly applied in the industry. The application of PVD coating technology is mainly divided into two categories: decorative coating and tool coating. The purpose of decorative plating is mainly to improve the appearance, decorative performance and color of the workpiece, and to make the workpiece more wear-resistant and corrosion resistant, so as to prolong its service life; This aspect mainly applies to various fields of the hardware industry, such as door and window hardware, locks, bathroom hardware and other industries. The purpose of tool plating is mainly to improve the surface hardness and wear resistance of the workpiece, reduce the friction coefficient of the surface, and improve the service life of the workpiece; This aspect is mainly used in various cutting tools, turning tools (such as turning tools, planers, milling cutters, drills, etc.), various hardware tools (such as screwdrivers, pliers, etc.), various molds and other products
