Corrosion- Preventative, Super-hydrophobic Coatings for Landing Gear

ABSTRACT: USAF Landing gear are subject to extreme corrosion. Processes are used to extend component life without introducing additional modes of failure. Corrosion can still occur if compromised by wear or damage. A breakthrough processing Diatomaceous Earth (DE) was patented by Oak Ridge National Labs. It allows the treatment of particles so that water cannot coexist with DE. This is referred to as Super Hydrophobic (SH) and repels water. SHDE would create a barrier within existing plating/paint/coating for the life of the component. The objective of this effort is to demonstrate increased corrosion resistance by applying SHDE to existing paint and platings used on USAF Landing Gear assets. A Business Case Analysis and Return on Investment would support the decision to implement across the entire DoD. BENEFIT: Research to develop a coating process which will economically reduce corrosion rates can have benefits for all commercial & military landing gear. ES3 expects: Reduction in corrosion rates Increased corrosion protection in paint and dry film lubricants and as a sealant and in threaded fasteners Non Hydrogen embrittling
