Hardide coatings can coat complex shapes, internal and out-of-sight surfaces, and complicated geometries uniformly.

The Chemical Vapour Deposition application process means that the coating crystallises uniformly across the surface of the part and can achieve full coverage of difficult to reach areas and complex geometries that cannot be coated by other treatment methods.

The coating can be targeted to reach only designated or internal surfaces of complex components, enabling new design possibilities for components used in demanding environments.

A Hardide-coated spring illustrates the toughness and flexibility of the coating

The Hardide coating does not crack or delaminate after repeat deformations of the substrate, showing superior flexibility for a hard coating – which is often brittle. The coating protects the spring against erosion, abrasion and corrosion. It is tough but flexible and doesn’t spall or deteriorate under high load or impact.
