PVD Coatings

PVD coatings are an essential process to reducing abrasion, corrosion and friction, among other wear situations, in tools and components for a wide range of industries. Our coatings effectively improve product functionality, life and performance while decreasing tool downtime. This improved tool and manufacturing process performance leads to overall increased customers productivity and profitability.

Physical Vapor Deposition (PVD) describes a group of vacuum coating processes. Components and tools are coated using arc vapor deposition with temperatures greater than 450°C. A strong bond between the coating and the substrate is formed without losing hardness, creating a surface protection in the microstructure of the base material. Some of our PVD coatings are biocompatible and/or have food safe grade.

Advantages:

• Possible combinations with friction reducing layers
• Variable coating structure (nanostructures, multi-layer, monolayer)
• Decoating by chemical and mechanical means
• Very good adhesion on the substrate
• Very good reproduction of textured and polished surfaces
• Very good maintenance of dimensional accuracy and contour-true coating
• No hardness reduction
• No influencing of the crystalline structure of the steel with suitable material selection
• An overall world-class selection of abrasion resistant PVD & DLC coatings
