Optical Surface Studies of Titanium and Titanium-Aluminum Alloys with Application to the Mechanism of Passivity and Non-Destructive Testing.

Abstract

Optical reflectance studies and Auger spectroscopy have been used to study Ti and Ti-Al alloy surfaces to study mechanisms relative to the formation of passive surfaces. Instrumentation has been developed for rapid data acquisition so that growth kinetics of oxide formation on the surface can be followed with non-destructive optical techniques. The use of synchrotron radiation has been an important tool in the surface studies. The measured optical reflectivity of titanium and titanium-aluminum are discussed in the light of new theoretical calculations. New theoretical methods in the analysis of Auger data has resulted in a significant improvement of information about the chemical environment of the surface. (Author)
