Description

ABSTRACT: There is a need to identify, qualify, and certify post-repair corrosion-inhibiting self-healing coatings in order to inhibit further corrosion on aluminum substrates. Many technologies have been developed in academia and industry to reliably identify visible and hidden corrosion on aluminum surfaces and components, restore lost coating material, or create a barrier to future corrosion. The research team at Luna Innovations Incorporated has developed a comprehensive system for the corrosion protection of aerospace components. Luna"s self-healing and anti-corrosion additives can be applied using chrome-free, low-VOC water based primers and we have a strong relationship with established paint manufacturers to meet MIL-SPEC requirements. Luna"s coating system will be suitable for aerospace aluminum alloys, titanium, and composites. By working closely with an aircraft maintenance consulting group, Luna will be able to address potential issues as identified by Depot and Air Force customers, as well as validate that the coating materials and application methods for sustained corrosion protection on war-fighting systems will be quick, mobile, financially viable, and reliable. BENEFIT: The total annual US cost estimates for corrosion related expenses are in excess of $300 billion, or 3.1% of the GDP. Much of the costs are associated with the maintenance of metal materials; 20% of the estimated corrosion-related costs involve scraping and repainting steel structures. A self healing coating will be beneficial to any industry sector that suffers from corrosion, such as infrastructure, transportation, utilities, and production and manufacturing. A durable, thermally stable, autonomous self healing corrosion protection coating will increase serviceable lifetime, reduce costs and improve operational efficiencies. Chrome-free and low-VOC coating systems will also provide an environmentally conscious solution to corrosion.
