Laser Surface Modification for Improving Corrosion Resistance of Steels Used in Coal-Fired Power Systems

65496 Future fusion magnet systems, as well as high energy physics (HEP) superconducting magnets, require the use of insulation systems capable of withstanding significant mechanical loads at both cryogenic and elevated temperatures, while also enduring high doses of radiation. New magnet designs have put an increased demand on the insulation, requiring that it withstand higher radiation doses, higher temperatures, and higher stresses. Conventional epoxy-type insulation systems do not meet the higher operational requirements of these new devices. This project will develop and evaluate innovative, radiation-resistant electrical insulation materials, fabricated as high-pressure laminates (HPL) using unique organic hybrid systems. In Phase I, both organic and inorganic components for the production of new HPL materials will be selected, based on their radiation-resistance, and a corresponding high-pressure lamination process will be developed. Processing properties such as fabric impregnation, tack, resin flow, and pressure lamination will be examined. Specimens will be fabricated and tested for mechanical and electrical properties and evaluated use in large-scale production. Commercial Applications And Other Benefits as described by awardee: Insulators with improved radiation-resistance; improved mechanical, electrical, and thermal properties; along with ease of fabrication should significantly reduce the cost of magnet fabrication and extend the useful lifetimes of magnets in future fusion and HEP devices.
