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.
IPG is a short writing of Ion Plating Gold, which it is a technology of arc and sputtering combined to deposit Gold thin film on luxury products, especially on jewerly indusry like: necklace, wedding rings, ear rings, watches, handbag accessories etc.
The Jewelry materials are mostly stainless steel 316L, brass, or alloy. After exclusively pre-treatment, jewelry manufactures can use our IPG gold plating machine directly to get the 18K rose gold or 24K real gold coatings, which highly enhance the products life and value.
Royal Technology has developed and produced 6 sets IPG exclusively using machine for coating service ceneters. The IPG machine main components:
1. Cylinder Arc unit or ( steered circular cathodic arc sources)
2. Planar Ion Source for Plasma cleaning before PVD coating
3. DC Sputtering Cathode of Ag ( Gold) deposition
4. MF Sputtering Cathode of TiN film coating
We provide you not only the coating machine but the total coating solutions, turnkey-project service is available.
Please contact us for more specifications, Royal Technology is honored to provide you total coating solutions.
