| Abstract Scope |
Barnacle adhesion on steel in marine applications is enabled by the protein-based cement that the crustacean secretes, which results in metal corrosion. Despite its economic and safety repercussions, very little is known about the mechanisms behind this protein-influenced corrosion (PIC) process. In this work, we investigate PIC by comparing the electrochemical processes at play when a marine grade steel is exposed to different proteins, including CP20, bovine serum albumin and lysozyme. Our results show that PIC is function of the absorptivity of proteins to the steel surface, which points to adsorption-induced chemical dissolution of iron as the PIC mechanism. These findings play a critical role in the design and formulation of solutions for corrosion prevention. |
