We have been coating aerospace components since 2005 when we engineered a solution for BAE Systems on the Eurofighter Typhoon. The initial testing and development of the coating led to a new Typhoon specification. The coating is currently going through aerospace test programs with Airbus and AgustaWestland among others.
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 matches hard chrome in thickness and hardness and out-performs the material in corrosion and wear resistance. Hardide-A coats internal surfaces and complex shapes uniformly and has anti-galling and fatigue resistant properties.
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.
*Published as “L.Vernhes, et al., Alternatives for hard chromium plating: Nanostructured coatings for severe-service valves, Materials Chemistry and Physics (2013)” and available at http://dx.doi.org/10.1016/j.matchemphys.2013.03.065.
Typical applications include:
- Compressor blades
- Landing gear
Hardide Coatings has AS 9100:Rev C. certification and is working towards Nadcap approval.
