Hardide nanostructured tungsten carbide coatings have been approved by Airbus, BAE Systems and Leonardo Helicopters. They can vary in hardness (typically 400 - 1600 Hv) and thickness (typically 50 - 100 microns) depending on the application and all can coat internal as well as external surfaces and complex geometries.

Hard Chrome, Cadmium and HVOF Replacement

Hardide-A is an environmentally compliant and technically superior replacement for hard chrome plating (HCP), cadmium and HVOF coatings. It matches the standard thickness (50-100 microns) and hardness (800-1200 Hv) of HCP and outperforms the material in several critical areas including enhanced protection against corrosion and chemically aggressive media, wear, galling, fretting and fatigue. Like all Hardide coating variants, it is truly conformal with a smooth ‘as coated’ surface finish and can be ground and super-finished if required. In tests, Hardide-A set a new benchmark and demonstrated a better high cycle fatigue endurance than HCP and exceptionally good corrosion resistance when exposed to a salt-fog environment. Testing by Airbus has shown Hardide-A to have superior fretting fatigue performance.

Hardide coatings can be applied to a wide range of metallic substrates including ferrous and nickel-based alloys, and most grades of stainless and carbon steels. A low temperature variant (sub 350OC) increases the range of suitable substrate steels.
