The electrochemical effect of the component materials on the overall corrosion behavior of the composite wire was elucidated. The formation of silver chloride corrosion product on the corroding silver core limited ionic transport therefore restricted further dissolution at the silver metal surface. Galvanic action between a Co-20Cr-35Ni-10Mo cathode and a silver anode was examined. Dissolution rate of the silver core in a composite wire obtained from immersion tests in a physiological solution of 9 g/L NaCl at 37°C was approximately 22 µm/y, i.e., 0.28 µg/y silver dissolved for a 37-µm-diameter silver core. Nearly all of the silver dissolved precipitate as silver chloride, i.e., approximately 0.37 µg/y. 4 Corrosion 67 ARTICULO Ha, H.M. 49479 Payer, J.H. 49480 180916 180916 0 0 0 0 248735 BAAB BAAB 2026-03-05 200052943 0 200052943 2026-03-05 23:50:58 2026-03-05 ARTICULO
