Nano Structured PVD Coatings Services

Improving wear and corrosion resistance in different specimens has always been importantly considered, and various approaches are widely used such as selection of suitable materials for pieces or the application of coatings which reduces the erosion. On the other hand, the beauty of the components and equipment used in residential and office buildings (such as sanitary valves, handles and cabinet fittings), as well as bags and shoes fittings, is also imperative. Many different methods have been developed to modify the surface of the parts and improve the beauty for instance application of coatings by conversional, thermal, metallic and deposition methods. Particularly, application of nanostructured coatings increases the hardness and corrosion resistance compared to thicker coatings. One of the common methods for applying nanostructured coatings is physical vapor deposition (PVD). This method provides the ability to create a thin layer with a thickness of less than 100 nm and provides a good adhesion and uniformity on the substrate. On the other hand, color is the most important feature of the decorative coatings. The most well-known hard decorative coating is TiN. Applying TiN coating on a smooth substrate, provides an attractive finish and brings a high hardness and wear resistance. This yellow coating is applicable on metal surfaces such as titanium, steel, aluminum, brass and Zamak.
