Aircraft typically comprise multiple materials, each exhibiting unique electrochemical properties. When they are exposed to harsh marine and global environments, the difference in material properties can lead to severe galvanic corrosion, causing safety risks, costly repairs, and reduced readiness.

The present approach for considering galvanic incompatibilities is simplistic and static. It is simplistic in that the only thing it takes into account is the galvanic potential difference between two adjacent materials. An estimate of the galvanic corrosion severity is usually based on some form of galvanic potential table, as in MIL-STD-889. However, in mixed…

For years, the solution to repairing aerospace coatings has required a lengthy grounding of aircraft in order to perform the repairs. No one wants to dismantle an in-demand aircraft to repair it for corrosion – and now we don’t have to.

This updated standard defines and classifies the galvanic compatibility of electrically conductive materials and establishes requirements for protecting coupled materials against corrosion with attention directed to the anodic member of the couple.

The Simcenter conference was very interesting, providing a great opportunity to learn more about the present software tools and also the trends in future development.

The demand for lightweight design and better fuel-efficiency in the aerospace industry has reflected a significant increase in usage of more lightweight materials such as CFC (Carbon Fiber Composite), titanium and aluminum alloys.
