Abstract
SUMX HAS DEMONSTRATED CONCEPTUALLY NEW COATINGS FOR CORROSION PROTECTION WHICH MAINTAIN METALS IN A PASSIVE CONDITION DUE TO ELECTRON TRANSFER BETWEEN METALS AND IMMOBILIZED REDOX CENTERS IN COATINGS. "PINNING" OF SUBSTRATE POTENTIAL PROTECT ELECTROCHEMICALLY THE REDOX COUPLES IN THE COATINGS, THEY ARE MORE EFFECTIVE THAN CONVENTIONAL COATING INHIBITORS IN USING ADSORPTION. SUMX COATING HAVE AN ENHANCED CAPABILITY TO TOLERATE PINHOLES, HOLIDAYS, AND COATING RUPTURES. IN PHASE I, SUMX JWILL TEST ADHESION AND CORROSION IN ACIDIC AND CHLORIDE-CONTAINING SYSTEMS. PHASE I WILL BE RESTRICTED TO IRON AND STAINLESS STEELS TO ESTABLISH COATINGS FEASIBILITY. (PHASE II WILL RESEARCH TO A1 AND TI ALLOYS AND DETAILED COATINGS FORMULATIONS.) COATED MATERIALS WILL BE STUDIED IN A RANGE OF ENVIRONMENTS. COATED METALS SHOULD BE MORE RESISTANT TO STRESS CORROSION CRACKING THAN CONVENTIONAL STEELS. WITH THE COATINGS, IT SHOULD BE POSSIBLE TO USE LESS EXPENSIVE AND MORE COMMON METALS THAN NORMALLY FOUND IN CORROSION ENVIRONMENTS. COATED METALS SHOULD SINGNIFICANTLY INCREASES PROTECTION AGAINST CREVICE CORROSION, CATASTROPHIC FAILURES, CORROSION AT LIQUID INTERFACES,AND CORROSION IN VARYING ENVIR0NMEMTS.
