2022-03-16

The coated workpiece of the PVD coating machine is processed in a vacuum chamber. Physical vapor deposition (PVD) coating technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating, and vacuum ion coating. The vacuum coating machines corresponding to the three classifications of PVD coating machine technology include vacuum evaporation coating machines, vacuum sputtering coating machines, and vacuum ion plating machines. In recent decades, vacuum ion plating technology has developed rapidly and has become one of the most advanced surface treatment methods today. The PVD coating we often talk about refers to vacuum ion coating. Let's learn about the PVD coating machine coating principle!

　　 PVD coating machine The coated workpiece is processed within a vacuum chamber. Physical Vapor Deposition (PVD) coating technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating, and vacuum ion coating. Vacuum coating machines corresponding to the three categories of PVD coating machine technology include vacuum evaporation coating machines, vacuum sputtering coating machines, and vacuum ion plating machines. In recent decades, vacuum ion plating technology has developed rapidly and has become one of today's advanced surface treatment methods. The PVD coating we often refer to is vacuum ion coating. Let's learn about the PVD coating machine coating principle introduction!

　　PVD coating machine technology uses low-pressure, high-current arc discharge technology in a vacuum state. By gas discharge evaporation of the target, the evaporated substance and gas are completely ionized. The acceleration effect of the electric field allows the evaporated substance and its reactants to deposit on the workpiece.

　　Characteristics of PVD coating machine coating: The film layer of PVD coating machine coating technology has high hardness, wear resistance (low friction coefficient), corrosion resistance, and chemical stability. The service life of the film layer is longer. At the same time, the film layer can greatly improve the appearance decoration performance of the workpiece.

　　Types of film layers that can be plated by a PVD coating machine: PVD coating technology is a micron-level coating and an environmentally friendly surface treatment method with no pollution. It can produce various single metal films such as aluminum, titanium, zirconium, and chromium, as well as nitride films. Thickness of PVD coating layer - The thickness of the PVD coating layer is in microns and is thin, usually 0.3 m ~ 5 m, with the thickness of the decorative coating layer generally being 0.3 m ~ 1 m. Therefore, it has little impact on the original size of the workpiece and can improve the various physical and chemical properties of the working surface without requiring post-processing after electroplating.

　　Regarding this, the PVD coating machine manufacturer points out that its working principle is actually very simple. In a vacuum state, argon ions formed by electron bombardment of argon are bombarded again against the target through an orthogonal magnetic field. The target ions are deposited on the workpiece surface to form a film. In this way, the headlamp coating machine manufacturer needs to consider three aspects related to the uniformity of the film layer thickness: vacuum state, magnetic field, and argon gas. Adjusting the vacuum state requires an intake system. Each intake port must be started simultaneously with consistent intensity. This can adjust the uniformity of inhalation. If the inhalation is uneven, the pressure in the vacuum chamber may be uneven. Pressure has a certain impact on the movement of ions. In addition, the inhalation time must also be controlled. Too short will lead to insufficient vacuum, but too long will waste resources, but with the existence of a vacuum machine, this is not a problem with proper control.

　　Types of colors of film layers that can be electroplated using PVD coating machine coating: Currently, PVD coating machine coating can produce film layers in the following colors: deep golden yellow, light golden yellow, brown, bronze, gray, black, gray-black, and seven colors. By controlling the relevant parameters of the coating process, the color of the coating can be controlled. After the coating is completed, relevant instruments can be used to measure the color to ensure that the electroplated color meets the requirements.
