In an effort to understand the kinetics and mechanisms of gas-phase metal oxidation reactions, experiments were continued in an apparatus which uses RF heating and laser radiation for the production of the metal vapor and time- of-flight mass spectrometry for product identification and quantitative measurements of reactants and products. Measurements were continued on the oxidation of thorium and uranium by molecular and atomic oxygen, as well as N2O and rate constants were measured.

The report presents the preliminary results of a laboratory experiment involving the production of metal vapor, using two techniques (laser radiation and RF induction heating), and the measurements of reactants and products resulting from the mixing of metal vapors with oxygen by the use of time of flight mass spectrometry. Preliminary values for the heat of vaporization, ionization potential (for metal, monoxide, and dioxide) for thorium, as well as the reaction rate are reported. (Author).

This book presents experimental data and recent results of model calculations on the formation of natural oxide film on metal surfaces and of metal hydride formation. Such films are responsible for corrosion, friction, and wear of metallic materials. Describing mostly the authors own research, this monograph gives an overview of models suitable for metal-gas reactions and demonstrates how complex metal-gas interactions can be analyzed by standard procedures of chemical kinetics. The book, and the data and equations it contains, will be useful to researchers in surface science, condensed-matter physics, and materials science.

The book is concerned with understanding the fundamental mechanisms of high temperature alloy oxidation. It uses this understanding to develop methods of predicting oxidation rates and the way they change with temperature, gas chemistry and alloy composition. The focus is on designing (or selecting) alloy compositions which provide optimal resistance to attack by corrosive gases. . Emphasises quantitative calculations for predicting reaction rates and the effects of temperature, oxidant activities and alloy compositions. . Uses phase diagrams and diffusion paths to analyse and interpret scale structures and internal precipitation distributions . Provides a detailed examination of corrosion in industrial gases (water vapour effects, carburisation and metal dusting, sulphidation) . Text is well supported by numerous micrographs, phase diagrams and tabulations of relevant thermodynamic and kinetic data . Combines physical chemistry and materials science methodologies.
