TURBINE COMPONENT HAVING SURFACE COOLING CHANNELS AND METHOD OF FORMING THE SAME

摘要

PROBLEM TO BE SOLVED: To reduce a pressure loss of a coolant flow and reduce stress concentration at an interface between an inlet opening and a channel.SOLUTION: A component (200) of a turbine engine (10) includes a substrate (202) that includes a first surface (204), and an insert (210) coupled to the substrate proximately to the first surface of the substrate. The component also includes a channel (230). The channel is defined by a first channel wall (234) formed in the substrate and a second channel wall (236) formed by at least one coating (212) disposed on the first surface of the substrate. The component further includes an inlet opening (240) defined in flow communication with the channel. The inlet opening is defined by a first inlet wall (242) formed in the substrate and a second inlet wall (248) defined by the insert.SELECTED DRAWING: Figure 1
