PVD Surface Coatings
Uddeholm is able to offer our customers the latest PVD (Physical Vapour Deposition) coating technology. Our PVD coatings can help improve performance and tool life, which also allows components to function in environments they otherwise may not be able to operate in.
We offer a full service experience, providing our clients not only with coatings assistance, but also advice on material selection and heat treatment specifications. This complete solution allows Uddeholm to ensure that our customers are receiving the best quality throughout their product supply chain.
TIGRAL coating is designed for tools in need of very high resistance against oxidation and abrasion. It is a two stage coating process, composed of a Plasma Nitride and followed by a mono layered matrix coating. This mono-layered matrix composition creates a very ductile film ideal for abrasive environments such as die casting and hot forging. TIGRAL coating avoids the drawbacks associated with high temperature coatings, but easily matches their performance levels. The low temperature application process allows for the metallurgical characteristics of the steel to be maintained. The unique chemistry of TIGRAL offers protection from materials that corrosively attack the tool steel, which results in reduced adhesive wear and alloying between work and tool materials, enhancing part release and greater productivity.
VARIANTIC coating is a high performance coating consisting of a specially designed plasma-nitriding process combined with a low temperature nano-layered PVD coating. This nano-layered feature greatly reduces stress and improves ductility, which increases coating longevity by preventing microcracks in the film. VARIANTIC coating was developed to avoid the distortions and disadvantages associated with high temperature coating processes such as CVD and TD coating, all while providing equivalent results. This coating allows for tools to be easily stripped and re-coated multiple times to maximize tool life without damage to the substrate. VARIANTIC coating is ideal for high pressure applications where adhesive and abrasive wear of the tool is significantly reduced providing impressive production enhancements.
