Thin Film Substrate
As the most beautifully luminescent and valuable metals on Earth, Gold's ability to throw light, reflect energy and resist tarnishing. PVD or Physical Vapor Deposition Gold Sputtering is commonly used in the watch and jewelry industry to produce coatings that are hard and durable and won’t rub off with constant contact with the skin or clothes and lose it sheen.
PVD Gold Sputtering is also used for coating circuit panels and electronic components due to its excellent conductivity, for coating optical fibers, batteries and high end faucets and fixtures. Gold Sputtering processes are invaluable for biomedical implants that serve as radiopaque coatings that are visible in x-rays and lifesaving procedures like coating tissue samples to make them visible for scanning under electron microscopes.
Gold Sputtering coatings are a thin film deposition process where gold or a gold alloy is bombarded with high energy ions in a vacuum chamber resulting in the gold atoms or molecules being “Sputtered” into the vapor and condensing on the substrate to be coated such as jewelry, circuit boards or medical implants.
PVD Gold Sputtering is frequently conducted as a DC Sputtering process which is among the simplest and least expensive types of sputtering equipment. Gold is also commonly applied as a thin film PVD process via Thermal Evaporation Deposition where it is evaporated in a low pressure environment with an electrical resistive heating element, or as Electron-beam Vapor Deposition where the gold is heated with an electron-beam in a high vacuum which then condenses on the substrate to be coated. PVD Gold Sputter Coating is applied in the high energy plasma “Fourth state of nature” environment and is able to apply coatings on a single atom layer with extreme purity. It usually makes for the hardest and strongest bonding to the surface to be coated where durability is key. It is the easiest to control the color of the gold coating with the PVD process.
