SUMX CORPORATION HAS INVENTED AND DEMONSTRATED CONCEPTUALLY NEW AND INNOVATIVE COATINGS FOR CORROSION PROTECTION. SUMX PROPOSES TO TEST AND DEVELOP THESE COATINGS FOR USE ON STEELS AND STRUCTURAL MATERIALS IN CHLORIDE ENVIRONMENT SUCHAS MIGHT OCCUR IN TRANSPORTATION SYSTEMS. THE CORROSION RESISTANCE AFFORDED BY THIS METHOD IS BASED ON ELECTRON TRANSFER BETWEEN THE METAL AND IMMOBILIZED REDOX CENTERS IN A COATING SO AS TO MAINTAIN THE METAL IN A PASSIVE CONDITION. THIS "PINNING" OF THE SUBSTRATE POTENTIAL MAY PROVIDE PROTECTION AGAINST LOCALIZED, AS WELL AS UNIFORM CORROSION MODES. THE REDOX COUPLES MAY BE EITHER APPLIED DIRECTLY OR INCORPORATED IN A POLYMER. THE RESULTING COATING TENDS TO ACT AS A REDOX BUFFER MAINTAINING THE SUBSTRATE METAL IN A PASSIVE STATE. THE COATING IS ALSO MORE PROTECTIVE WITH REGARDS TO PINHOLES AND HOLIDAYS IN THECOATING BECAUSE IT IS AN ELECTROCHEMICALLY ACTIVE COATING. SUMX WILL TEST CARBON STEEL AND STAINLESS STEEL SAMPLES AND ELECTRODES IN ENVIRONMENTS WITH AND WITHOUT CHLORIDE PRESENT. TESTING WILL BE CONDUCTED ON BASE AND COATED ELECTRODES. THE RESULTS WILL BE EVALUATED FOR THE EFFECTIVENESS IN COMBATING UNIFORM, PITTING, AND CREVICE CORROSION.
