Abstract
SUMX CORPORATION HAS DEVELOPED AND DEMONSTRATED CONCEPTUALLY NEW COATINGS FOR CORROSION PROTECTION. THE CORROSION RESISTANCE AFFORDED BY THIS METHOD IS BASED PM ELECTRON TRANSFER BETWEEN THE METAL AND IMMOBILIZED REDOX CENTERS IN THE 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. IN THE PROPOSED WORK, SUMX INTENDS TO ADAPT THE ELECTROACTIVE COATING METHOD TO RELATIVELY LOW CHROMIUM CONTENT 400 SERIES STAINLESS STEELS. THE BEHAVIOR OF THESE COATED MATERIALS WOULD THEN BE STUDIED IN RANGE OF ENVIRONMENTS. THEIR RESISTANCE TO BOTH UNIFORM AND LOCALIZED CORROSION WILL BE CHALLENGED. THE RESULTS OF THE PROGRAM CAN BE USED TO ESTIMATE THE SAVING IN STRATEGIC MATERIALS OBTAINABLE BY REPLACING CONVENTIAL STATNLESS STEELS WITH ELECTROACTIVE COATED ONES IN CORROSIVE APPLICATIONS. THE COATED MATERIALS MAY ALSO BE MORE RESISTANT TO STRESS CORROSION CRACKING THAN CONVENTIAL STEELS. THIS POSIBILITY WOULD BE EVALUATED IN THIS PROGRAM AND THOROUGHLY TESTED IN PHASE II WORK.
