Abstract: A tip rail cooling insert for attaching into a tip rail pocket in a tip rail of a turbine blade is disclosed. The insert includes a first inner layer defining at least one first insert cooling channel therein, the first inner layer including a pair of spaced legs defining a first coolant collection plenum with at least the tip rail pocket for directing coolant from at least one internal cooling cavity in the turbine blade to the at least one first insert cooling channel. Each of the pair of spaced legs has an angled outer end configured to accommodate rounded inner corners of the tip rail pocket. A first outer layer is on a first side of the first inner layer, and a second outer layer is on a second side of the first inner layer.

Abstract: A ball for a ball-chute in a turbine component, the turbine component, and a method of using the ball, are provided. A ball may include a ball body made of a pre-sintered preform (PSP) material. The ball body has an opening defined therethrough having a first cross-sectional area. A hollow member is fixed within the opening defined through the ball body. The hollow member has a second cross-sectional area smaller than the first cross-sectional area of the opening, and is made of a material having a melt temperature higher than a melt temperature of the PSP material. The method includes positioning the ball and brazing the ball in place. The hollow member maintains fluid communication through the ball after the brazing, and allows customized metering of the coolant flow therethrough.
