High-temperature oxidation of alloys

Oxidation of Metals, 1970
Some recent developments in the understanding of the oxidation of alloys at elevated temperatures are reviewed, with special reference to binary and ternary alloys upon which many commercial materials are based. Following an initial classification of alloy systems, certain basic principles and their limitations are considered, including factors ...

Oxide Electrodes at High Temperatures

1985
High temperature fuel cells and electrolysers based on solid yttria stabilized zirconia electrolytes typically operate at 1000°C to reduce polarization losses. Much of the published work on electrode reactions has been carried out on precious metal electrodes (1–4).

The high temperature oxidation of tetrafluoroethylene

The Journal of Chemical Physics, 1977
The high temperature oxidation of tetrafluoroethylene (C2F4) in excess argon has been studied behind reflected shock waves. Kinetic data were obtained for three fuel/oxidant ratios and all experiments were carried out in the temperature and total pressure ranges 1670–2500 °K and 4.0–6.9 atm, respectively.

High-temperature oxidation of MoSi2

Journal of Materials Science, 2010
Oxidation behavior of MoSi2 was investigated in air over the temperature range of 1400–1700 °C. Spallation of the SiO2 scale did not occur at any temperature, and Mo5Si3 formation did not happen below 1700 °C. A change in the rate-controlling mechanism was detected within the temperature range of this study.

The oxidation of vanadium at high temperatures

Journal of the Less Common Metals, 1965
Abstract The oxidation of vanadium has been studied in the temperature range 700°–;1050°C. On admission of oxygen to the metal, considerable heat is evolved which at higher oxygen pressures may be sufficient to produce a self-maintaining “burning” reaction. The pressure required to produce burning decreases with increasing temperature.

High temperature oxidation of acetaldehyde

Symposium (International) on Combustion, 1977
The gas phase kinetics of the first stage of acetaldehyde oxidation were studied from 1030°K to 1115°K in a turbulent flow reactor which permits accurate determination of the spatial distribution of stable species. Experiments were performed in nitrogen at atmospheric pressure containing 0.1–0.75% acetaldehyde and 0.16–8% oxygen.

High-temperature oxidation of copper

Russian Chemical Reviews, 2013
Data on the kinetics and thermodynamics of high-temperature oxidation of copper are generalized. The attention is focused on the catastrophic oxidation of copper contacting some low-melting oxides. The results of experimental and theoretical studies of the last 10 years concerning the catastrophic oxidation of copper are analyzed.

High-temperature oxidation of ZrAl

Journal of the Less Common Metals, 1988
Abstract The oxidation of ZrAl in dry oxygen in the temperature range 800–1100 K follows a parabolic rate law. An activation energy of 86.4 kJ mol−1 was estimated. During the oxidation, aluminium diffuses from the oxide layer to the ZrAl bulk, thus forming a ZrAl2 phase very close to the oxide-alloy interface.

The high temperature oxidation of butadiene

Symposium (International) on Combustion, 1985
1,3-Butadiene oxidation and pyrolysis at approximately 1100 K were studied by obtaining species profiles in a chemical kinetic flow reactor. The mechanism postulated for the oxidation of butadiene is based on the intermediate species observed, their relative order of maximum concentration, some assumptions about the high temperature reactions of ...

Oxidation of copper at high temperatures

Oxidation of Metals, 1971
The kinetics and mechanism of copper oxidation have been measured over the temperature range 900–1050°C and the pressure range 5×10−3 to 8×10−1 atm. It has been shown that, at the pressures lower than the dissociation pressure of CuO, the oxide scale formed on flat fragments of the copper specimens is compact and composed of a single layer, adhering ...
