Abstract: A method for forming a vertically cracked thermal barrier coating is disclosed including positioning an article relative to a heat source. The article includes a thermal barrier coating disposed on a first surface of a substrate, and the substrate includes a second surface distal across the substrate from the first surface. Heat is applied locally to at least one discrete portion of the second surface of the substrate. At least one vertical crack in the thermal barrier coating is formed disposed over the at least one discrete portion. An article is disclosed including a substrate and a vertically-cracked thermal barrier coating disposed on the substrate. The vertically cracked thermal barrier coating includes at least one vertical crack in the thermal barrier coating and at least one of a low density of less than 85% of a theoretical density for the thermal barrier coating and a selective crack distribution.

Abstract: The disclosure relates generally to recovering bond coat materials and barrier coat materials from co-mingled mixtures of bond coat and barrier coat materials (e.g., plasma overspray waste), and from mixtures of co-mingled bond coat and barrier coat materials stripped from a substrate. The disclosure also relates to recovering rare earth elements (e.g., yttrium) from a barrier coat of the co-mingled plasma overspray waste or mixture of co-mingled bond coat and barrier coat materials stripped from the substrate.
