<P>PROBLEM TO BE SOLVED: To provide gas turbine components having durability and reliability for use in a corrosive environment such as a turbine employing a low grade fuel, and also to provide a gas turbine equipped with the components. <P>SOLUTION: A gas turbine rotor/stator vane includes: a substrate made from an alloy containing Ni, Co, or Fe; a bonding layer made from an alloy and disposed over the substrate; and a thermal barrier coating disposed over the bonding layer. The thermal barrier coating includes: a thermal barrier layer of porous ceramics; an environmental barrier layer containing silica; and an impregnation layer having a silica-containing material in the pores of the porous ceramics. <P>COPYRIGHT: (C)2012,JPO&INPIT |
