The Coat With Excellent Sliding Properties
The WC/C PVD coating is made of a tungsten carbide carbon layer (a-C:Me) and yields significantly reduced friction and adhesive wear. Thanks to reduced friction one can expect, this coating system is ideally suited for the coating of parts sliding against each other (e.g. slides). WC/C is a special PVD arc technology, an Eifeler in-house development. Apart from reduced friction, the novel deposition method in our arc units delivers, above all, a coat with high adhesion strength.
WC/C coating is suited for the use on materials that can be subjected to coating temperatures exceeding 300° C. The reduction in friction the coat yields significantly improves the sliding properties of various tools, components and construction elements. The anti-friction effect also makes it applicable to e.g. hard coated machining tools.
