Abstract
The process of making an ingot for use as a feed stock for a coating process in which the ingot is vaporized to produce the coating material; the ingot being made by forming a billet of the alloy minus the reactive element with a rod of the reactive element of the alloy extending centrally through the billet and then shaping the billet to ingot size, the cross-sectional area of the rod having the same relation of the remainder of the area of the billet as the percentage of the reactive element in the alloy.
