Processing and Deposition of Nanocrystalline Oxide Composites for Thermal Barrier Coatings
Abstract
As described in a previous report 1, electrophoretic deposition (EPD) was used as the method for depositing thermal barrier coatings (TBC). In this report, we used the conventional technique of plasma spraying to deposit a CoNiCrAlY bond coat on the substrates. Following deposition of the plasma sprayed bond coat, electrophoretic deposition was used to deposit Al2O3-Y2O3-ZrO2 thermal barrier coatings. We examined the thermal stability of the TBC when applied on top of the plasma sprayed CoNiCrAlY-based bond coat. Plasma spraying was compared to electrophoretic deposition as a method for bond coat deposition.
