Hauck Heat Treatment - Decorative PVD Coatings

Decorative PVD Coatings

Hard wearing PVD Coatings are excellent decorative coatings to replace traditional electroplated and painted finishes such as gold plating as well as provide alternative colour finishes. Our decorative PVD Coatings are typically <1.5 micron thick and will not tarnish, chip, fade or corrode. e.g. PVD ‘gold titanium’ plating has extremely high hardness (10 – 20 times harder than gold) which provides excellent scratch and wear resistance compared to traditional decorative gold electroplating which is typically 0.5 microns thick. Although extremely hard, it is worth noting that the thickness of the PVD coating applied is however very important – very thin PVD coatings (0.01 microns) will also scratch. It is also worth noting that PVD ‘gold titanium’ is not the same as PVD deposited gold coating.

Our services provide scratch resistance in metals including 440c stainless steel. PVD coating can deliver a gold coloured coating, adding surface hardening and excellent colour for clients. PVD adds colour and a highly scratch resistant finish.

Thin decorative PVD coatings are typically deposited on top of stainless steel. The PVD coatings can also be applied directly to other materials such as titanium or nickel alloys. We can deliver a decorative black coating as well as PVD Gold, PVD Brass, and PVD Bronze. Other coating colours are available. These provide highly scratch resistant finishes whilst maintaining the original surface texture of the product - contact us for more detail.

Colour coating of steel using PVD achieves an excellent result - PVD Gold is a favoured colour for many high end consumer (and business products). Materials which can be PVD coated include;

• Stainless steel
• Titanium
• Architectural steel
• All other steels

The range of PVD colors are achieved by depositing different metals with reactive gases to form metal nitrides and metal carbonitrides. Decorative PVD coatings add real benefit to metal surfaces - hardening, scratch resistance and many other properties. Avoiding paint finishes on metal is achieved through applying hard colour coatings.

Surface finish

Surface finish of the part to be coated does play a significant role in the appearance and final colour obtained. PVD coatings can be deposited onto a polished, brushed, blasted, rumbled or satin finish as well as ground or machined finishes. These different finishes will affect the final visual appearance of the colour.

Popular colours available include gold, light gold, anthracite black, gunmetal, bronze and champagne.
