What is the principle of PVD vacuum coating?

PVD is physical vapor deposition, which is an advanced surface treatment technology and widely used in the world. Its working principle is that under the vacuum condition, the gas or evaporated substance is partially ionized by gas discharge, and the evaporated substance or its reactant is deposited on the substrate while the gas ions or evaporated substance ions bombard. It has the characteristics of fast deposition speed and clean surface, especially the advantages of strong film adhesion, good winding and wide plating range. Adopt the world's advanced magnetron sputtering ion plating and multi-arc ion plating process equipment, and on this basis, innovate together with international experts. With more than ten years of valuable experience in decorative electroplating industry, we provide customers with the most suitable coating processing scheme. \ x0d \ Properties of PVD coatings \ x0d \? Metal appearance has a uniform and durable surface, which permanently maintains a good appearance under various basic air and direct sunlight environmental conditions. The color is deep and bright. \x0d\？ It is economical and can reduce the time and cost required for cleaning and polishing electroplated brass or gold. Clean PVD film with soft cloth and glass cleaner. \x0d\？ Harmless to the environment, avoiding chemical poisoning and VOC emission. \x0d\？ It is biocompatible. \x0d\PVD coating characteristics \x0d\? Excellent adhesion, can be bent over 90 degrees without cracking and peeling (PVD coating has strong adhesion and durability). Other technologies, including electroplating and spraying, can't be compared with it. \x0d\？ Any imaginable design pattern can be etched. \x0d\？ Can be used for indoor decoration or outdoor. \x0d\？ Vacuum coating, oxidation resistance and corrosion resistance. Corrosion resistance, chemical stability, acid resistance. PVD-resistant coating for mobile phone shell. \x0d\？ The coated shell is easy to remove paint and fingerprints. \x0d\？ In strong sunlight, salty wetlands and urban environment, it will not lose its luster, oxidation, fading, falling off and bursting. Highly wear-resistant, scratch-resistant, not easy to scratch. Platable materials are extensive, and the bonding force with the substrate is strong. \x0d\PVD decorative coatings series \x0d\PVD can be plated on stainless steel, copper, titanium-zinc-aluminum alloy and other metals. Gold, brass, rose gold, silvery white, black, smoky gray, copper, brown, purple, blue, burgundy, bronze and other colors, and can provide the required color and quality according to your requirements. EMI film, semi-permeable film, transparent film and non-conductive film can also be plated on plastic products. \x0d\PVD application scope \x0d\PVD technology is widely used in the processing and manufacturing of door and window hardware, kitchen and bathroom hardware, lamps, seafood, jewelry, handicrafts and other decorative products. \x0d\ Now PVD has become quite popular in the field of daily hardware, and many world-leading hardware manufacturers have started the research and development and mass production of PVD products. The rich colors of PVD make it very easy to match, and its excellent environmental resistance, easy cleaning and colorfastness make it deeply loved by consumers. Especially copper-based coatings are widely used to replace copper and copper-plated products all over the world.
