Characterization, Testing & Failure Analysis


NASC provides metallographic support for materials characterization used in component design evaluations, failure investigations, and R&D support. We have provided testing on static strength and ductility of various aluminum alloys after exposure to SO2/salt spray.

Composite Materials


NASC evaluates the risks associated with low-cost manufacturing processes and have developed manufacturing concepts that address the fabrication, processing, and assembly of composite materials. The major focus of recent efforts has been on fuselage and wingtip radomes for the E/A-18G platform.

Organic & Inorganic Coatings


NASC work with military customers in developing and testing alternative electroplating processes and pre-paint surface treatments designed to eliminate chromium and cadmium based coatings on U.S Navy aircraft.

Corrosion Prevention & Protection


NASC has experienced personnel that provide support to the Navy corrosion effort and Corrosion Focus Teams. Our fleet experience, logistics background, and knowledge of training requirements of our personnel have been instrumental in identifying alternative means for future support and associated cost, determining alternative ownership and funding resources, and performing risk assessments of corrosion. We also supported the aircraft wash cycle rate of corrosion study on all CNARF F-18 aircraft using NALDA, Snap Shot, and Deck Plate programs to geographically track corrosion activity, man-hour expenditure, corrosion treatment and preservation documentation ashore.

Operational Fluids & Chemicals


NASC has developed new technologies such as low-Volatile Organic Content (VOC), non-VOC, non-toxic, non-polluting and non-chemical materials and application methods. We completed a two year demonstration and validation of a newly developed Low VOC, high performance, long lasting, corrosion preventive compound (CPC), named "Navguard", for internal airframe application to minimize the costs attributed to aging aircraft.

Environmental Protection & Pollution Prevention


Protecting the environment from pollutants and pollutant prevention is important to both NASC and the US military. We have assisted the NAWCAD Environmental Materials Program on a number of on-going RDT&E projects directed toward the reduction or elimination of hazardous materials. Our staff has prepared NAVAIR Team Environmental RDT&E Fiscal Year Project and Funding Profile Publications and Environmental Materials Program Phase Reports. We also maintain a library of the latest regulations and provide guidance to NAWCAD personnel developing compliant coatings and alternative pre-treatment and removal processes.
