Corrosion control and advanced materials research
Navmar engineers perform materials science research and development with the aim of developing improved and
advanced materials for use by the US military. Military vehicles, whether, air, water or ground use some of
the most advanced and cutting edge materials invented. Navmar has over thirty years experience in metals, ceramics,
polymers and composites materials characterization. We are a member of the Aerospace Materials Technology Consortium (AMTC).
Our expertise includes:
Characterization, Testing & Failure Analysis - Navmar works closely with our military customers to provide metallographic support for materials characterization used in component design evaluations, failure investigations, and R&D support. We determine the changes in static strength and ductility of various aluminum alloys after undergoing multiple active deployments and to exposure in SO2/salt spray.
Composite Materials - We assess 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 and Inorganic coatings - Navmar works closely with our military customers in the development and testing of alternative electroplating processes and pre-paint surface treatments designed to eliminate chromium and cadmium based coatings from use on Navy aircraft.
Corrosion Prevention and Protection - Corrosion is a huge problem on military equipment - especially in the sea water environment. Navmar has experienced personnel that provide support to the Navy corrosion effort and Corrosion Fleet Focus Team (CFFT). 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. Navmar 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 and Chemicals - Military vehicles require all sorts of fluids and chemicals for lubrication, pneumatics, cleaning, and operation. Navmar works closely with our customers to develop new technologies such as low-Volatile Organic Content (VOC), non-VOC, non-toxic, non-polluting and non-chemical materials and application methods. We perform sample preparation, testing and analysis. We recently 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 Navmar and the US military. Navmar has years experience in assisting 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 assisted NAWCAD in preparing publications such as NAVAIR Team Environmental RDT&E Fiscal Year Project and Funding Profile, and the 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.
