Decorative hard coatings have to meet variety of requirements such as attractive colors and high wear resistance. For luxury consumer goods such as watch components, writing instruments or spectacles, some manufactures want to maintain both the high wear resistance of PVD and the “gold plate” label which provides the product with a “high quality” image. So a 3 to 5 μm layer of gold plating must therefore be deposited onto a (TiN+Au) PVD layer. This multi-layer method creates a high level of internal stress leading to adhesion defects. A complete process has to be set up in order to reduce the internal stress leading to adhesion defects. Royal Technology Developed the IPG process widely used on watch bands, watch dials, jewelry like rings, necklace, bracelets, writing instruments, luxury consumer accessories. We developed and followed the PVD coating processes strictly. Exterior and Interior of PVD vacuum chamber cleaning ( ultrasonic wave cleaning, Plasma bombardment cleaning) ; exterior and interior of PVD vacuum chamber drying ( drying oven, inside of chamber drying by heaters up to 250℃ to improve the coating film adhesion.) Royal Technology has 3 standard machines .Cylinder Arc unit or ( steered circular cathodic arc sources) .Planar Ion Source for Plasma cleaning before PVD coating .DC Sputtering Cathode of Ag ( Gold) deposition .MF Sputtering Cathode of TiN film coating
