Abstract

The use of parts made of polymer composite materials in the design of aircraft poses additional challenges to prevent contact corrosion. Polymer composite materials differ significantly in electrochemical properties from metal materials used in airframe construction. The article presents studies of the corrosion behavior of electrically conductive metal coatings in contact with carbon fibers by the method of constructing anodic and cathodic polarization curves, as well as the results of corrosion testing of fasteners with protective coatings in a salt fog chamber.
