Aerospace Materials Chemistry Materials Science aerospace ceramic combustion environment high temperature hydroxyl species oxidation materials Si silicon titanium dioxide TiO2 Ti-O-H transpiration method transpiration technique volatility water vapor Titanium (Ti) and silicon (Si) containing materials are of high interest to the aerospace industry due to its high temperature capability, strength, and light weight. A continuous exterior oxide layer is desirable to reduce the oxidation rate of these two materials. At high temperatures, water vapor plays a key role in the volatility of materials including oxide surfaces. This study first evaluated several hot-pressed Ti and Si-containing compositions at high temperatures as a function of oxidation resistance. This study also evaluated cold pressed titanium dioxide (TiO2) powder pellets at a temperature range of 1400°C - 1200°C in water containing environments to determine the volatile hydoxyl species using the transpiration method. The water content ranged from 0-76 mole % and the oxygen content range was 0-100 mole % during the 20-250 hour exposure times. Results indicate that oxygen is not a key contributor at these temperatures and a volatile Ti-O-H species has been identified. 2008 English text Cleveland State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=csu1239291812 http://rave.ohiolink.edu/etdc/view?acc_num=csu1239291812 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
