More Information
Summary:The Naval Surface Warfare Center, Carderock Division (NSWC-CD) Corrosion and Coatings Engineering Branch (Code 613) performed corrosion evaluation and coating compatibility testing on panels prepared with poly(styrene-co-catechol)-based adhesive pretreatments for improved coating adhesion and improved corrosion resistance for U.S. Marine Corps ground vehicles. Ground vehicles are composed of diverse materials/substrates, including steel, stainless steel, composites, and aluminum. Loss of CARC adhesion to different metallic substrates, such as 6061 and 5083 aluminum (aluminum alloys that have other elements added to pure aluminum to enhance its properties), stainless steels, fasteners, and carbon steels has been documented across USMC ground vehicles (Figures 1-2). An uncoated, flanged stainless steel fastener was placed in the center of each cell, isolated from the panel with a rubber grommet.
