Independent tests have proven Hardide-A improves the fatigue life of metal components by 4.5% compared with uncoated substrates. The coating set a new benchmark, demonstrating a better high cycle fatigue endurance than HCP and exceptionally good corrosion resistance when exposed to a salt-fog environment.
Like all Hardide coating variants, Hardide-A is truly conformal with a smooth ‘as coated’ surface finish offering enhanced protection against corrosion and chemically aggressive media, wear and galling. It eliminates the need for post-coating shot peening operations and can be ground and super-finished if required.
Hardide-W is a potential replacement for Cadmium coating providing a corrosion barrier rather than a sacrificial mode and matching the typical thickness of Cadmium. Hardide-W is also truly conformal with a smooth ‘as coated’ finish and provides enhanced protection against galling, corrosion and fretting.
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 350°C) increases the range of suitable substrate steels.
