The adhesive proteins stick to steel and form a complex with iron ions in the alloy, creating a protective coating
A synthetic version of the proteins found in barnacle adhesives forms a coating on steel surfaces that inhibits corrosion from salt water. They form tough films on metal surfaces, preventing exposure to seawater, but they can leach toxic chemicals into the environment, harming living organisms. Other researchers have made glues for bone or dental repair from this protein because it adheres strongly to inorganic substrates, says materials scientist and engineer Ali Miserez, who led the work.
