  • Advances in Polymer-to-Metal Bonding for Underwater Environments
    /metal bonds will hydrolyze in the presence of moisture, but, lead to the understanding that consequential debonding cannot be stopped. High pH environments, a consequence of cathodic action in the environs of ship hulls, especially aggravate the condition. In addition, thermal shock is found...
