A high temperature component such a gas turbine high temperature component, for example, constituting movable or stationary blade portion, thereby comprises a base material and a thermal barrier coating coated on a surface of the base material. The thermal barrier coating has a thermal barrier characteristic controlled in accordance with an environment to which a high temperature component is exposed so as to make substantially uniform a surface temperature of the base material. The thermal barrier coating comprises a thermal barrier ceramic layer having a thermal barrier characteristic capable of being controlled by varying a thickness thereof at portions of the thermal barrier ceramic layer.

1. A high temperature component comprising:a base material; and a thermal barrier coating coated on a surface of the base material, said thermal barrier coating consisting essentially of first and second layers, wherein the first layer comprises a MCrAlY alloy layer where M is selected from the group Cr, Co or Ni, wherein the second layer comprises a low thermal conductivity ceramic material comprising ZrO2 partially stabilized with Y2O3 and wherein the ceramic material of the second layer of the thermal barrier coating has at least one thermal barrier layer characteristic that affects its thermal conductivity and that varies over the surface of the thermal barrier coating according to a profile that provides essentially a uniform surface temperature on the surface of the base material.
