Abstract
Official abstract text for this publication.
An article, such as a bucket, a blade, a nozzle, a vane, a strut, a fuel nozzle, a combustion casing, and a transition piece, the article having a damping coating comprising approximately 8 wt % to approximately 15 wt % Y 2 O 3 and approximately 19 wt % to approximately 28 wt % Ta 2 O 5 with the balanced weight of ZrO 2 is presented.
First claim
Opening claim text (preview).
What is claimed is: 1. An engine component having a damping coating comprising about 8 weight (wt) % to about 15 wt % Y 2 O 3 and about 19 wt % to about 28 wt % Ta 2 O 5 with a balanced weight of ZrO 2 , wherein the damping coating includes tetragonal zirconia, wherein a c axis of a unit cell of the tetragonal zirconia is about 1% to about 2% larger than orthogonal axes a and b of the unit cell, and wherein the c axis of the unit cell is configured to transform to at least o…
