Abstract
A method of fabricating a fuel injector is disclosed which includes the steps of forming a structural portion of a fuel injector from an alloy having a first mechanical property, and then adding an alloy having a second mechanical property on a surface area of the structural portion to enhance the mechanical properties of the fuel injector.
Claims3
A method of assembling a fuel injector comprising the steps of:
- a) producing a feed arm of a fuel injector from a first alloy;
- b) depositing by laser additive deposition a second alloy onto a specified surface area of the feed arm;
- and
- c) forming a braze joint between an injector component and the feed arm at the specified surface area, wherein the injector component and the second alloy have a greater brazeability than the injector component and the first alloy.
