Abstract
The present method for machining a part includes wire electro-discharge machining the part to create a recast layer, and then removing a zinc content of the recast layer without substantially altering the remainder of the initial composition make-up of the recast layer. The final composition make-up of the recast layer is substantially identical to the initial composition make-up except for the removed zinc content.
Claims14
A method for machining a part of a gas turbine engine, comprising:
- wire electro-discharge machining the part using a wire electrode having a zinc component to create a recast layer having an initial composition make-up including a zinc content and at least one other material content as a result of the wire electro-discharge machining of the part;
- and
- removing at least a portion of only the zinc content from the recast layer without altering a remainder of the initial composition to produce a final composition make-up of the recast layer, the final composition make-up being identical to the initial composition make-up except for the removed zinc content.
