摘要:
A protective coating system is described that is characterized by fluid impermeability and a reduced coefficient of friction. The coating system includes a carbide-based thermal spray composition; a low friction layer; and a sealant impregnated into the low friction layer. Unlike conventional materials, the coating systems of the present invention achieve and maintain sealing surfaces, without adversely impacting lubricity, wear resistance and corrosion resistance during the service life of the coated component.
