Abstract

A method of forming a thermocouple ( 12 ), including: depositing a first material on a component ( 10 ) to form a first leg ( 14 ); depositing a second material through a mask ( 30 ) to form a pattern ( 50 ) on the component ( 10 ), the pattern ( 50 ) forming a plurality of discrete second leg junction ends ( 20 ) and a continuous patch ( 52 ) of the second material comprising indiscrete lead ends of the second legs ( 16 ), each second leg junction end ( 20 ) spanning from a respective junction ( 18 ) with the first leg ( 14 ) to the continuous patch ( 52 ); and laser-ablating the continuous patch ( 52 ) to form discrete lead ends ( 22 ) of the second legs ( 16 ), each lead end ( 22 ) electrically connected to a respective junction end ( 20 ), thereby forming discrete second legs ( 16 ).

First claim

The invention claimed is:

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…
