AbstractADA Technologies Inc. has developed an electrochemical strippable coating technology for the removal of radioactive contaminants from conductive surfaces. The proposed three-phase SBIR project would apply this electrochemical technology to cleaning surfaces prior to welding or brazing. The process will eliminate grease, dirt, and rust from conductive surfaces using electro-polishing techniques. Once the strippable coating fully cures the material along with the contaminants can be stripped off of the surface, leaving only a clean uniform surface behind. The remaining waste is a plastic film which can be disposed in standard municipal garbage or possibly recycled. During the Phase I portion of this three-phase SBIR project, ADA will clean titanium plates using standard pickling methods and the electrochemical strip-coat method. The surface of the coupons will then be analyzed for cleanliness using SEM and post-weld strength using tensile tests.
