Aluminum Alloy Corrosion Control and Prevention

Added: Dec 09, 2013 1:32 pm The Office of Naval Research (ONR) is soliciting full proposals for the development and transition of tools and technologies to reduce operations, maintenance, and support costs associated with 5000 series aluminum sensitizations.

Specifically ONR is interested in receiving full technical proposals to develop the following research areas:

- Field Portable, Non-Destructive Evaluation Degree of Sensitization Detection Tool: A robust portable NDE Degree of Sensitization (DoS) detection system that can quantitatively detect and assess DoS in a large area on aluminum ship hulls to provide improved condition-based maintenance decisions for ship structural integrity and health monitoring (Proposals for this area are being requested under this BAA).

- Maintenance Prediction Degree of Sensitization Analysis Software Packages: The assessment of future maintenance requirements for 5000 series aluminum ship structures based on current shipboard DoS levels (Proposals for this area are being requested under this BAA).

- Aluminum Alloy Desensitization Surface Treatment and Repair Tool: Repair tools for sensitization related pitting and cracking (Proposals for this area are being requested under this BAA).

- Lightweight Coatings: The developed exterior coating system should maintain a 5000 series aluminum alloy surface temperature of less than or equal to 104°F and provide adequate corrosion protection characterized by no localized corrosion or pitting on surfaces (Proposals for this area are being requested under this BAA).

Proposers may submit to one or more of the Aluminum Alloy Corrosion Control and Prevention research areas noted above. However, a separate standalone proposal is required for each research area.
