Abstract

A contiguous duplex microstructured material comprises a nanostructured material having two structural states, for example, a duplex microstructured coating. One state comprises substantially nanostructured features, while the second state substantially comprises microstructured features. A duplex nanostructured coating can be made by thermal spraying a reconstituted nanostructured material onto a substrate under conditions effective to form a coating comprising more than one structural state.
