Method of coating a composite material and a coated edge of a composite structure

Abstract

A method of coating a composite material and an associated coated composite structure are disclosed to provide increased wear resistance and surface protection. The edge of the composite material may be coated so as to provide protection for the edge. A method of coating a composite material includes applying an adhesion promotion layer to the composite material. The adhesion promotion layer includes a binder paint and a plurality of metal particles within the binder paint. The metal particles may be irregularly shaped. The method also includes applying a thermal spray coating to the adhesion promotion layer. The thermal spray coating may include a twin wire arc bond coating on the adhesion promotion layer and a high velocity oxygen fuel spray coating on the twin wire arc bond coating.
