Title:

Eco-Friendly Process for the Preparation of Corrosion Resistant Sealed Anodized Coatings on Aircraft Aluminium Alloy 
Value Proposition:

A chromate free pretreatment process for the corrosion protection of aerospace aluminum alloy. 
Summary Application:

Aluminum alloy structural components
Advantages:
  • At present no chromate free technology is available for the corrosion protection of AA 2024 alloys used in aircraft applications.
  • An indigenous and cost effective process has been developed.
  • The coating system is chromate free corrosion protective system for aluminum alloys with societal impact.
  • This process can also be used in automobile sectors.
