A wear resistant coating protects against corrosion and erosion of the thin metal protective sheath on turbomachinery applications. The coating has a metal layer overlaid by a ceramic layer. Multiple metal and ceramic layers can make up the coating with the layers varying in thickness allowing the layers nearer the substrate to remain more malleable to bend with the sheath and those layers nearer the top of the coating to be more brittle and resistant to wear. A cold spray metallic layer applied to the substrate provides a lightweight, flexible layer beneath the corrosion and erosion resistant protective multilayer coating.
