Abstract
A method for improving the quality of a zirconia-based coating deposited on a metal-based substrate is disclosed. The method comprises the step of plasma-spraying zirconia powder of substantially uniform particle size onto the substrate. The disclosure further relates to an improved powder source material for use in a plasma. The source material is zirconia powder having a uniform particle size, and optionally, a uniform particle density. The use of such a material results in improved thermal barrier coatings for various substrates, such as those found in a turbine engine.
