Processing and Characterization of Porous Oxide Coatings.

Abstract

The goals of this research project were to develop processing methods for fabrication of porous oxide coatings with a range of pore contents and to develop characterization methods for porous coatings. Research focused on controlling porosity in coatings prepared by the deposition of metal alkoxide solutions and coatings formed by a low temperature chemical reaction between alumina and phosphoric acid. The effect of processing conditions on pore content and pore size were established. Results can be divided into three categories: (1) development and control of porosity in alkoxide-derived titania coatings; (2) characterization of macroporous coatings and (3) porosity in alumina/aluminum phosphate coatings. Two categories of results concern the development of new processing methods for ceramic coatings and the scientific understanding of porosity control. The second category is a new method for the easy characterization of pore content in macroporous coatings.
