Gun Tube Coatings in Distress

Abstract

The effects of thermal, chemical, and mechanical stress components of erosion on the degradation and failure of current and potential future gun tube coating materials are investigated. Potential failure mechanisms at the interface are shown and discussed. The interfacial coating/base material stress calculation methodology, including coating crack formation and coating adhesion criteria, is presented. Possible erosion mitigation concepts are also presented to counteract the formation of cracks in the coating.
