Abstract

This paper reports how the microstructural information, obtainable for thick plasma-sprayed ceramic deposits by small-angle scattering can be used to explore the relationships among the feedstock or spray process conditions, the anisotropic void and crack microstructures of the deposits, and technologically important deposit properties such as thermal conductivity. The application of near-surface small-angle scattering, to characterize the microstructure of sub-millimeter-thick coatings on the substrate, is also reported for the first time.
