Development of X-ray Methods for Analyzing Rough-Wear Surfaces on Ceramics.

摘要

This report summarizes research performed by Virginia Polytechnic Institute and State University under subcontract to Oak Ridge National Laboratory. The work, funded by the Energy Conversion and Utilization Technologies Program of the US Department of Energy, began January 1, 1983, and ended September 30, 1987.The purpose of the research was to develop novel x-ray diffraction and fluorescence methods for probing the near-surface (<1 (mu)m deep) zone of worn ceramics. An important aspect of the work in regard to fundamental tribology research was to overcome the difficulties associated with x-ray analysis of rough surfaces. Fully and partially stabilized zirconia (PSZ) were selected as the materials to be examined by the x-ray techniques being developed. The specific characteristics of the worn ceramic surface of most interest were phase content, particle size, and near-surface strains. This summary outlines the major findings of this work. Details of the mathematical analysis may be found in the four cited open-literature references. Material in this report has been abstracted from the original manuscripts and reprints of these references. Each reference is separately outlined. 1 ref., 4 figs.
