THIS PROPOSAL ENVISIONS DETERMINING THE FEASIBILITY OF USING PHOTOFABRICATION TECHNOLOGY TO PRODUCE LOW COST SEAWATER CORROSION SENSORS.

THIS PROPOSAL ENVISIONS DETERMINING THE FEASIBILITY OF USING PHOTOFABRICATION TECHNOLOGY TO PRODUCE LOW COST SEAWATER CORROSION SENSORS. UNLIKE CONVENTIONAL ELECTROCHEMICAL CORROSION SENSORS WHICH MEASURE ONLY INSTANTANEOUS CORROSION RATE, THE PROPOSED SENSORS WILL MEASURE BOTH INSTANTANEOUS RATE AND CUMULATIVE CORROSION. THE TENTATIVE DESIGN OF THESE SENSORS IS VERY COMPACT, ABOUT THE SIZE OF A POSTAGE STAMP. THE RESEARCH PROPOSED HEREIN COVERS BOTH THE DESIGN AND PROOF OF CONCEPT TESTING OF THE PROPOSED SENSORS. BECAUSE OF ITS WIDE USAGE IN SEAWATER PIPING SYSTEMS, 90/10 COPPER NICKEL, (C70600), WILL BE ONE OF THE ALLOYS STUDIED IN THIS RESEARCH; STEEL WILL BE THE OTHER. THE PRINCIPLES DEVELOPED IN THE RESEARCH ARE APPLICABLE TO OTHER MARINE ALLOYS, WHICH WOULD BE EVALUATED IN PHASE II.
