Ceramic coatings containing layered porosity

Abstract

Layered ceramic coatings in which some layers contain porosity as described as are methods for producing such coatings. The different layers have different compositions and/or are applied under different conditions. As applied, some of the layers have a Zone I structure and some have a Zone II/III type structure (as defined by Movchan). Heat treatment can be used to increase the porosity in the Zone I structure layers.
