Abstract
Articles transparent to infrared radiation and resistant to impact and wear are provided. The article comprises a substrate and a composite coating disposed over the substrate and extending from an interface with the substrate to an external surface. The composite coating comprises a first phase and a second phase. The second phase has a higher resistance to erosive wear than the first phase. The coating comprises a compositional gradient proceeding from a first composition at the interface of the coating with the substrate to a second composition at the external surface, the first composition comprising a higher concentration of the first phase than that of the second composition.
