Technical theory

PVD is the abbreviation of English Physical Vapor Deposition, which refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions to vaporize the target by gas discharge and ionize the vaporized substance and gas. The accelerated action of the electric field is used to deposit the evaporated substance and its reaction product on the workpiece.

Coating technology

Enhanced Magnetron Cathodic Arc: The cathodic arc technique is to deposit the film material by ionizing the target into a ionic state by a low voltage and a high current under vacuum conditions. The enhanced magnetron cathode arc utilizes the combined action of electromagnetic fields to effectively control the arc on the surface of the target, so that the ionization rate of the material is higher and the film performance is more excellent.

Filtering Cathodic Arc: Filtered Cathodic Arc (FCA) is equipped with a highly efficient electromagnetic filtration system that filters out macroscopic particles and ion clusters in the plasma generated by the ion source. After magnetic filtration, the ionization rate of the deposited particles is 100%. And the large particles can be filtered out, so the prepared film is very dense and smooth, has good corrosion resistance, and has strong binding force with the body.

Magnetron sputtering: In a vacuum environment, by the interaction of voltage and magnetic field, the target is bombarded with ionized inert gas ions, causing the target to be ejected in the form of ions, atoms or molecules and deposited on the base member. A film is formed thereon. Depending on the ionization source used, both conductor and non-conductor materials can be sputtered as targets.

Ion beam DLC: The hydrocarbon gas is ionized into a plasma in the ion source. Under the action of the electromagnetic field, the ion source releases carbon ions. The ion beam energy is controlled by adjusting the voltage applied to the plasma. The hydrocarbon ion beam is directed onto the substrate and the deposition rate is proportional to the ion current density. The ion beam source of the star arc coating uses a high voltage, so the ion energy is larger, so that the film and the substrate have good bonding force; the ion current is larger, so that the deposition speed of the DLC film is faster. The main advantage of ion beam technology is that it can deposit ultra-thin and multi-layer structures with process control accuracy of several angstroms and minimize defects caused by particle contamination during the process.

PVD technology in the application of bright strips

PVD vacuum coating technology can coat stainless steel surface, applied to stainless steel decorative strips and stainless steel edge strips. The surface corrosion resistance and wear resistance of the product are stronger than ordinary stainless steel, and it has strong resistance to salt spray corrosion and UV resistance. . The main colors are titanium black, gun black, sky blue, purple red, bronze, rose gold, titanium gold, champagne gold, brown, seven colors, coffee gold, water-plated red bronze, green bronze and so on. The PVD coloring technology is oxidatively modified and colored on the surface of stainless steel to maintain the basic structure and basic properties of the original stainless steel, and can be subjected to conventional molding and drawing processing. The colored surface has the advantages of colorful color, bright color, bright color, softness, elegance and smoothness.
