Corrosion and tribocorrosion performance degradation mechanism of multilayered graphite-like carbon (GLC) coatings under deep-sea immersion in the western Pacific
Source abstract
Abstract
Corrosion evolution of Cr/GLC multilayered coating exposed in the deep sea of the western Pacific after 342 days at various depths was investigated. Results showed that the atomic structure of the top-layer GLC layer remained almost unchanged after immersion, but severe corrosion across multi-scaled interfaces was significantly stimulated as the immersion depth increased. This further led to the weakening of coating density and adhesion strength, with the wear rate and corrosion rate being two orders of magnitude larger than those of the as-deposited coating. Therefore, reducing defect density and conductivity is the key to designing GLC coatings for deep-sea applications.
