Abstract

Methods of forming a cooling passage on a turbine component 200 having a component wall with an internal surface 212 and an external surface 214, are disclosed. An opening 220 is formed passing through the component wall and fluidly connecting the internal and external surfaces. The opening includes a metering section 222 extending from the internal surface to a metering end, and a diffuser area 226 extending from the metering end to the external surface. A preformed cap element is added to close a portion of the diffuser area to form the cooling passage with a diffusion section 242 extending from the metering end to the external surface. The preformed metal cap element includes a projection 244 extending internally of the external surface and into the diffusion area to define an internally facing section of the diffusion section. The cooling passage extends through the component wall and fluidly connects the internal surface and the external surface.
