Thermal Response of Titanium to Laser Radiation Including the Effects of the Oxidation Reaction.
Abstract
Experimental results from laser heating of oxide-coated titanium show instances where the temperature of the back face of thin sheets increases more rapidly than if the front face had absorbed 100% of the laser energy. This paper considers the effects of the exothermic oxidation reaction of titanium as the possible source of the additional energy necessary to produce the observed heating rates. An expression is obtained for the rate of oxidation of titanium as a function of temperature and is incorporated into a numerical analysis of the heat flow problem. Two different models are proposed and examined to see if they can produce the necessary temperatures to create a significant oxidation rate. It is concluded that the required additional energy to reproduce experimental results cannot be explained by the oxidation reaction as determined in this report.
