What is still a vision to others is for Surcoatec, the experts of innovative industrial plasma surface technology, core business. By changing the interfacial properties by means of macro - and micro-structuring in conjunction with the plasma surface technology the properties of technical surfaces can specifically set. Due to the profound expertise developed over years Surcoatec achieves a significant reduction of loss factors such as friction, wear, corrosion, reflection, among others.
With Surcoatec as partner you win a decisive advantage for the requirements of the so called Integrated Industry (Industry 4.0): increased performance and process stability, extending the service life and improve efficiency.
Shoulder to shoulder with its customers and the users of technology, Surcoatec develops tailor-made solutions far away from any standard. PVD and PECVD processes are combined with different mechanical processes for micro-structuring or plasma-based nano-structuring.
The plasma-enhanced chemical vapor deposition (PECVD or PACVD) operates at much lower temperatures than conventional thermal CVD. The layers synthesized exhibit a high density, are mostly of amorphous glassy structure, (which results in smooth surfaces), have a high hardness and show a good barrier effect (diffusion barrier, transmission barrier). The PECVD processes are particularly suitable to coat heat-sensitive materials of various forms as well as of internal surfaces of hollow bodies.
The source material for layer deposition is transferred under high vacuum into the vapor phase by means of evaporation or sputtering and is condensed back to a suitable substrate. Hard coatings, applied by PVD processes are particularly interesting for the coating of tools. Tool coatings are distinguished by a high hardness, a chemical and thermal resistance and they exhibit generally a typical metallic character. The coating temperature is preferably not exceeding 500 °C. Using PVD wear protective layers are applied on tools and components with a layer thickness of usually 500 nm up to 5 µm.
