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.
