The three proposed modes of corrosion protection brought about by the coating (i.e., a localized corrosion barrier, a sacrificial anode to supply cathodic protection of any exposed AA2024-T351, and active inhibitor release to facilitate chemical protection of AA2024-T351) have been verified to function simultaneously in dilute chloride solutions. The localized corrosion properties of the PTS-applied coating samples were not equal to the fully amorphous melt-spun ribbons even when ribbons were produced from feedstock powders. This inferior behavior in coatings was traced to various microstructural and physical defects. However, this inferior behavior cannot be attributed to feedstock powder composition since melt-spun ribbons made from feedstock powders had excellent localized corrosion properties. PTS coatings provided sacrificial anode-based cathodic protection and provided chemical protection afforded by Ce3+ release. 3 Corrosion 68 ARTICULO Tailleart, N.R. 52516 Gauthier, B. 52517 Eidelman, S. 52518 Scully, J.R. 27367 187128 187128 0 0 0 0 254947 BAAB BAAB 2026-03-06 200059233 0 200059233 2026-03-06 00:16:50 2026-03-06 ARTICULO
