We have been coating aerospace components since 2005 when we engineered a coatings solution for BAE Systems on the Eurofighter Typhoon, which led to a new Typhoon specification and ongoing production orders. In 2015, a new variant, Hardide-A, was approved by Airbus as a direct replacement for hard chrome plating on specific applications. The coating has also successfully completed the first of two test phases for approval on an application for Leonardo.
Hard Chrome Replacement
Hardide-A has been developed specifically to meet the needs of the aerospace industry and as a direct replacement for hard chrome which faces restrictions imposed by EU REACH and US OSHA regulations.
Hardide-A is a truly conformal coating for standard diameters, complex geometries and internal bores. During testing, Hardide-A set a new benchmark and demonstrated a better high cycle fatigue endurance than hard chrome and exceptionally good corrosion resistance when exposed to a salt-fog environment.
The coating is featured as an alternative for hard chromium plating for severe service valves in *Elsevier’s Materials Chemistry and Physics, the international journal on science, characterisation and processing of advanced materials. The article was independently authored by valve manufacturer Velan Inc, the Université de Montréal and Notre Dame University-Louize, Lebanon.
