Jewelry Decoration PVD Vacuum Plating Machine can achieve efficient coating, mainly due to its advanced physical vapor deposition technology and precise equipment design. The following are several key factors for its efficient coating.
Vacuum environment: The equipment performs coating operations in a highly controlled vacuum environment, effectively avoiding the interference of gas molecules on the coating process, ensuring the purity and uniformity of the coating layer, and this environment provides ideal conditions for the evaporation and deposition of the target material.
Physical vapor deposition technology: PVD technology uses physical methods (such as arc discharge) to evaporate and ionize the target material, and then accelerates the deposition on the jewelry surface under the action of an electric field. This process is direct and efficient, and can quickly form a dense coating layer.
Precise control: The equipment is equipped with a precise automatic control system that can monitor and accurately adjust various parameters in the coating process in real time, such as the evaporation rate of the target material, deposition time, substrate temperature, etc. This precise control ensures the quality and stability of the coating layer.
Efficient energy utilization: During the PVD coating process, the evaporation and deposition of the target material mainly rely on the conversion of electrical energy into thermal energy and kinetic energy. This equipment optimizes the energy utilization efficiency, making the coating process more efficient and energy-saving.
System Summary
Arc Discharge: An electric arc or arc discharge is an electrical breakdown of a gas that produces an ongoing electrical discharge. The current through a normally nonconductive medium such as air produces a plasma; the plasma may produce visible light. An arc discharge is characterized by a lower voltage than a glow discharge, and it relies on thermionic emission of electrons from the electrodes supporting the arc.
Multi-arc ion coatings can be deposited in a wide range of colors. The range of colors can be further enhanced by introducing reactive gases into the chamber during the deposition process. The widely used reactive gases for decorative coatings are nitrogen, oxygen, argon or acetylene. The decorative coatings are produced in a certain color range, depending on the metal-to-gas ratio in the coating and the structure of the coating. Both of these factors can be altered by changing the deposition parameters.
Prior to deposition, the parts are cleaned so the surface is free of dust or chemical impurities. Once the coating process has started, all the relevant process parameters are continuously monitored and controlled by an automatic computer control system.
