<p>The present invention provides gas turbine components having durability and reliability for use in a corrosive environment such as a turbine employing a low grade fuel, and also provides a gas turbine equipped with the components. One of the components is a gas turbine bucket/nozzle comprising a substrate (10) made from an alloy containing Ni, Co, or Fe, a bonding layer (11) made from an alloy and disposed over the substrate (10), and a thermal barrier coating (12, 13, 14) disposed over the bonding layer. The thermal barrier coating includes a thermal barrier layer (12) of porous ceramics, an environmental barrier layer (13) containing silica, and an impregnation layer (14) having a silica-containing material in the pores of the porous ceramics.</p> |
