Nitron MC

Graphitic carbon-based coatings for highly loaded wear components

Wallwork Cambridge's Nitron MC provides tribological benefits in an array of applications

Wallwork Cambridge Nitron MC coatings provide benefits for highly loaded parts. When applied to sliding steel surfaces Wallwork Cambridge Nitron MC - an in-house developed Tungsten Carbide Carbon (WC-C) deposited by Magnetron Sputtering technology - reduces adhesive wear and surface fatigue as well as reducing the potential for seizure even in dry running situations.

The demanding performance criteria imposed by the drive for weight reduction and lower fuel consumption can subject critical components to exceptional loads and wear. The most important wear mechanism which occurs on highly-loaded sliding or rolling parts is adhesive wear; or cold welding.

Carbon coated components when compared to nitrided surfaces and nickel and chromium-coatings exhibit improved wear-resisting performance. In particular Nitron MC (WC/C) coatings offer the proper combination of low coefficient of friction, high hardness and high abrasion resistance required by highly loaded automotive, aerospace and machine parts.

The visually appealing anthracite colour has made the coating popular for hard wearing decorative films demanded by the luxury goods market. For instance watches, phone covers and jewellery products have been aesthetically augmented by the deposition of Nitron MC providing a scratch free, smooth and fashionable surface finish.

Developed and optimised by Wallwork Cambridge, NitronTM WC/C coatings are made of hard tungsten carbide particles in a soft amorphous carbon matrix
