Kinetics And Mechanisms Of Titanium Wire Oxidation, Tanmay P. Engineer
Boise State University Theses and Dissertations
The kinetics and mechanisms of oxidation of titanium wire were assessed using a large test matrix in Ar-20% O2 at 800 to 1200°C, and N2-20% O2 at 1000°C, for 0.5 to 24 hours. The effects of geometry on oxidation were evaluated by investigating the behavior of six high purity Ti wires with diameters varying from 50 to 2000 μm, with an objective of producing hollow TiO2 tubes.
Oxidation behavior was characterized by measuring oxide thicknesses and morphology by optical microscopy, and the phases were characterized using a combination of SEM and TEM. The kinetics was …
