Abstract
A method for treating metal workpieces, including non-ferrous metal workpieces such as Titanium. The metal workpieces are heat soaked for a predetermined amount of time in a furnace at a predetermined temperature. An interstitial element is introduced into the area adjacent to the surface of the metal workpieces until a predetermined concentration of the interstitial element exists in the area adjacent to the metal workpieces. The treated metal workpieces are then cooled, resulting in the metal workpieces having a diffusion region formed which extends into the body of the metal workpieces. The region has a gradient of the interstitial element formed therein.
