Abstract

Results of the Phase I program have shown that DLN films are highly resistant to corrosive attach by salt water, acids, and alkalis, as well as abrasion by sand. Mechanical strength and hardness much higher that steels was obtained. Stability of the films after exposure to elevated temperatures was confirmed. The Phase I program has thus demonstrated that DLN films are well suited for protecting naval weapons compounds against erosion and corrosion while performing the thermal management and strengthening functions. DLN also has the potential to perform the function of low observable coating surfaces. In the strength of demonstrated properties, ART has put together a vertically integrated team for Phase II effort. The goals of the proposed program are i) to optimize DLN films for use in protecting naval steels against corrosion and erosion, while improving fatigue and thermal management characteristics, ii) to optimize DLN films foruse in protecting infrared windows against erosion, and iii) to optimize DLN coatings for commercial applications. The proposed Phase II program includes research in mechanisms of failure, technology development, performance optimization and commercialization efforts. Collaborative arrangements are included with federal laboratories, potential end-users and ART research partners. The proposed work is likely to successfully address problems faced in naval applications, and also technology development to a stage where other application areas can also benefit. The likelihood of success is high due to demonstrated properties, as well as the involvement of recognized and experienced teams. Phase II funds will be used to leverage significant additional industrial, federal and internal research support.
