Abstract
A method of creating a controlled interior surface configuration of passages within a substrate, particularly cooling passages of nozzles or buckets of a gas turbine, involves the hot isostatic pressing of a leachable passage insert whose surface carries the female image of the desired interior surface configuration inside the substrate followed by leaching of the insert from the substrate.
Claims11
A method of creating a controlled surface configuration of passages within a substrate which comprises assembling said substrate and a leachable passage insert whose surface carries a female image of a desired passage surface configuration, hot isostatic pressing said substrate against said insert, and leaching said insert from said substrate to create the desired passage surface configuration in said substrate.
