Abstract
The invention provides a method for the metallizing of precision machine parts coupled with heat-treatment and machining to insure the minimal handling the remachining generally required due to dimensional distortion resulting from the standard heat-treatment used in hardening the metallized coating.
Claims3
A method of manufacturing a coated precision metal part, said method comprising preliminarily heat treating a metal part at a first temperature cycle sufficient to effect dimensional distortion thereof, conforming the preliminarily heat treated metal part to a dimension, forming a metal coating on a least a portion of the conformed metal part, and secondarily heat treating the coated conformed metal part at a second temperature cycle insufficient to effect significant dimensional distortion thereof, whereby the secondarily heat treated metal part conforms to said dimension.
