Abstract

Official abstract text for this publication.

A method of making a fluid injector for a gas turbine engine includes depositing material onto a piece of tube stock. The method includes machining the deposited material into a fluid injector component. Depositing can include laser cladding the material onto the piece of tube stock. The method can include placing or flowing braze into a braze joint location between the deposited material and another fluid injector component and forming the braze into a braze joint in the braze joint location.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of making a fluid injector for a gas turbine engine comprising: depositing material onto a piece of tube stock; and machining the deposited material into a fluid injector component; wherein the piece of tube stock is a prefilmer, wherein depositing material includes depositing material on only a portion of a circumference of an outer surface of the piece of tube stock, and wherein machining includes forming a passage through the deposited material and through the piece of tube stock to form a passage through the deposited material and into an interior of the piece of tube stock, wherein the passage comprises a joint surface; and placing or flowing braze into a braze joint location comprising the joint surface, between the deposited material and a fluid injector feed arm and forming the braze into a braze joint in the braze joint location to join the feed arm to the prefilmer. 2. The method as recited in claim 1 , wherein depositing includes laser cladding, electron beam cladding, cold spaying, and/or plasma spraying the material onto the piece of tube stock.
