The Combination of Gold Plating and High Wear Resistance of PVD

Key Words:PVD, Gold plating, Electroplating, Adhesion

ABSTRACT

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 deposit 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.

WHY A COMBINATION OF “ GOLD PLATING” AND PVD?

Gold is still the most widely used color for decorative applications, and this is unlikely to change. For gold colored decorative hard coatings, the current state-of-the-art technique involves depositing a thin top layer of gold alloy onto a basic hard coating consisting of TiN. Unfortunately, gold alloy sputtering is a non-reactive process and for each different gold alloy a very definite color is obtained (for deposition temperatures around 200℃)

This process must not alert the final gold color without changing the gold target. Some manufactures also want to maintain both the high wear resistance of PVD and the “Gold plated” label which provides the product a high quality image. For these three seasons:

High wear resistance of the PVD layer

Gold plated label

Wide range of gold color provided by the final electroplating

A reliable process must now be found which allows a thick (3 to 5 μm) of electroplated gold onto a TiN+Au layer.

RTAC1250-SP The arc and sputtering integrated series equipment can produce highly reflective black and bronze films specifically for high quality decorative coatings.

RTSP1213-DC It is a sputtering system with PECVD process to deposit thin film on hydrogen fuel cell power module. Fuel Cell Vehicles is the newest technology for the next generation of environmentally friendly cars. The main advantage and technological progress compared to commonly used batteries like dry cell need to undergo a recurring recharging process, but hydrogen fuel cell power modules only require Hydrogen and Oxygen reaction to generate power for driving.

RTAC1215-SPMF This coating system is exclusively used for DPC (Direct Plating Copper) ceramic substrates process. The DPC ceramic substrates are widely used in various applications: for instance in high brightness LED to increase the longevity because of its high heat radiation performance, Semiconductor equipment, in microwave wireless communication, military electronics, various sensor substrates, aerospace, railway transportation, electricity power and much more.

RTEP-0913 Evaporation coating plant is applied to CsI film deposition for X-Ray Imaging devices. It is an advanced technique to evaporate CsI on the screen to create high quality images. The high-resolution performance allows this application to be extremely efficient and disruptive in the medical instrument, nuclear energy industry, security checking and inspection, high energy physics subjects and more.

Shanghai Royal Technology also successfully designed and developed Cube and Cylinder model large size Aluminum Vacuum Metalizing System which is used for Automotive Logo Board Coating.
