The Influence of Laser-Induced Oxidation on the Absorptivity of Titanium.
Abstract
Polished commercially pure (CP) titanium and Ti-6Al-4V alloy specimens were oxidized isothermally in a laboratory furnace for varying lengths of time. The grown oxide films of known thickness, surface conditions and major composition, were then subjected, along with unoxidized samples, to 10.6 micrometer laser radiation in air. Thermal response of the samples was measured. Oxidation effects were inferred by comparison of resulting thermal response curves for the initially oxidized and unoxidized samples. Room temperature reflectivity measurements were also taken of each sample prior to laser tests. In addition, absorptivities were inferred by comparing experimental versus computer generated thermal response curves. Computer modeling of experimental response data was also performed. A literature survey is included.
