Analysis of Marine Service Environment and Corrosion Mechanism of Naval Gun Barrel

Abstract

Except for erosion and wear, the corrosion also significantly affects the service life of naval gun barrel in marine environment. In view of a lack of research on the corrosion of naval gun barrel at present, the corrosion forms of naval gun barrel under the interaction effects of gun bore launching environment and marine corrosion environment were analyzed systematically. In addition, the research viewpoint of whole service life corrosion of naval gun barrel was put forward. And based on such research viewpoint, the corrosion mechanisms of the naval gun barrel for the three stages of having a Cr coating without any cracks, having a Cr coating with cracks and spalls, and having a bare barrel substrate were summarized.
