A cooling system for cooling of the squealer tip surface region of a high pressure turbine blade used in a gas turbine engine and a method for making a system for cooling of the squealer tip surface region of a high pressure turbine blade used in a gas turbine engine. The method comprises the steps of channeling apertures in a tip cap to a diameter of about 0.004′ to about 0.020′ to allow passage of cooling fluid from a cooling fluid source; applying a bond coat of about 0.0005′ to about 0.010′ in thickness to the tip cap such that the bond coat partially fills the channels; applying a porous TBC layer of at least about 0.003′ in thickness to the bond coat, such that the porous TBC fills the channels; applying a dense ceramic TBC layer over the porous layer; and, passing cooling fluid from a cooling fluid source through the channel into the porous TBC. The density of the dense TBC layer can be varied as needed to achieve desired cooling objectives. Because the channel exit is filled with porous TBC material, cooling fluid flows through the porous passageways in the porous TBC layer into the squealer tip. Although the passageways provide a plurality of tortuous routes, the increased density of the TBC in the dense ceramic layer provides a resistance to flow of the cooling fluid and effectively causes the cooling fluid to more efficiently spread through the TBC into the squealer tip before exiting into the gas stream at the outer surface.

1. A cooling system for cooling of the squealer tip region of a high pressure turbine airfoil used in a gas turbine engine comprising:a superalloy tip cap; a superalloy squealer tip extending outward in an engine radial direction from the superalloy tip cap into a hot gas stream of the engine; at least one channel having a first and second end, the first end terminating in an exit orifice located on a surface of the tip cap, the second end connecting to a cooling circuit located within a substrate, wherein the at least one channel has a diameter to permit an effective flow of cooling fluid; a bond coat having a thickness of about 0.0005′ to about 0.010′ applied to the tip cap surface, wherein the bond coat partially fills the exit orifice of the at least one channel; a layer of porous thermal barrier coating (TBC) having a first amount of predetermined porosity applied over the bond coat such that the porous TBC substantially covers the remainder of the exit orifice of the at least one channel; and, a layer of dense ceramic TBC applied to the porous layer of TBC, wherein the dense TBC layer has an amount of predetermined porosity so that it is less porous than the porous TBC layer.
