Deposition of Iron on the Surface of Titanium Microparticles

Abstract

: An Fe–Ti bimetallic system has been prepared by reducing Fe(III) ions on metallic titanium particles in an aqueous solution. Scanning electron microscopy and Auger electron spectroscopy have been used to examine the surface morphology of the particles and determine the elemental composition of their near-surface region. The material has been shown to consist of (1) aggregates ranging widely in size, from a few to several hundred microns, which are, in turn, agglomerates of smaller particles, about 100 nm in size, and (2) irregularly shaped, bulk, continuous particles. According to X-ray diffraction characterization results, the samples contain the metallic phases α-Fe and α-Ti.
