TURBINE ENGINE WITH YTTRIA-STABILIZED ZIRCONIA COATING AND A COATING SYSTEM CONTAINING A LAYER OF YTTRIA-STABILIZED ZIRCONIA

摘要

A turbine engine component is provided which has a substrate, a yttria-stabilized zirconia coating applied over the substrate, and a molten silicate resistant outer layer. The molten silicate resistant outer layer is formed from gadolinia or gadolinia-stabilized zirconia. A method for forming the coating system of the present invention is described.
