Abstract:
1. A method of forming a thermocouple on a contoured gas turbine hot gas path component, the method comprising: depositing a first material on the contoured gas turbine engine hot gas path component to form a first leg of the thermocouple; depositing a second material through a mask to form a pattern of the second material on the component, the pattern forming a plurality of discrete second leg junction ends and a continuous patch of the second material comprising second leg lead ends and excess second material connecting all of the second leg lead ends, each second leg junction end spanning from a respective junction with the first leg to the continuous patch; and laser-ablating the excess second material from the continuous patch while the continuous patch is uncovered to reveal the second leg lead ends, each second leg lead end electrically connected to a respective second leg junction end, thereby forming discrete second legs each comprising one second leg junction end and one second leg lead end, wherein the respective junctions are disposed on the component at locations effective to provide a temperature profile of the component during operation.
