Title: Quantitative analysis of thermal spray deposits using stereology

Abstract

Stereology deals with protocols for describing a 3-D space, when only 2-D sections through solid bodies are available. This paper describes a stereological characterization of the microstructure of a thermal spray deposit. The aim of this work is to present results on the stereological characterization of a thermal spray deposit, using two approaches known as DeHoff`s and Cruz-Orive`s protocols. The individual splats are assumed to have an oblate spheroidal shape. The splat size distribution and elongation ratio distribution of splats are calculated using quantitative information from 2-D plane sections. The stereological methods are implemented to investigate the microstructure of a water stabilized plasma spray-formed Al{sub 2}O{sub 3}-13wt.%TiO{sub 2}. Results are obtained with both protocols. The splat sizes range from 0 to 60 {micro}m and shape factors from 0.4 to 1.0. The splats within the deposit seem to be much smaller and thicker (i.e., lower spreading) than those of the first layer deposited onto the substrate. The approach described in this work provides helpful quantitative information on the 3-D microstructure of thermal spray deposit.
