PVD coating technology is an environmentally friendly surface treatment method that can truly obtain a micron bottom layer and is pollution-free. It can prepare various single metal films (such as aluminum, titanium, chromium, etc.), nitride films (TiN, ZrN, CrN, TiAIN ) and carbide films (TiC TiCN), and oxide films (such as TiO, etc.) PVD coating can currently produce film colors such as deep golden yellow, light golden yellow, brown, bronze, gray, black, gray-black, seven colors, etc. By controlling the relevant parameters in the coating process, the plated color can be controlled. After the coating is completed, the color can be measured with relevant instruments, and the color can be quantified to determine whether the plated color can meet customer needs.
The application of PVD coating technology is mainly divided into two categories, decorative coating and tool coating. The purpose of decorative coating is mainly to improve the appearance, decorative performance and color of the workpiece, while making the workpiece more wear-resistant and anti-corrosion to extend its service life. The main applications in this area are In various fields of the hardware industry, such as door and window hardware, locks, bathroom hardware and other industries, the purpose of tool coating is mainly to improve the surface hardness and wear resistance of the workpiece, reduce the friction coefficient of the surface, and increase the service life of the workpiece. In this regard Mainly used for surface treatment of scissors, turning tools, drill bits, various hardware tools such as screwdrivers, pliers, digital electronic products, and instrument casings.
