The oxidation behavior of Inconel 625 during the early stages (<150 min) has been studied at oxygen pressures (PO
2) of 0.12 kPa (0.9 torr) and 101.3 kPa (760 torr) in the temperature range of 1323 K to 1523 K by using TGA and between 873 and 1523 K by using XPS, AES, and EDS. The TGA results correlated well with those obtained by surface analysis of the oxide films. The results of XPS and AES ana...... hiện toàn bộ
Thermodynamic Simulation for the Environmental Prediction of High-Efficiency Waste-to-Power Plant BoilerSpringer Science and Business Media LLC - - 2015

In order to characterize the complicated corrosive environment around superheater tubes in advanced waste-to-power (WTP) boilers, thermodynamic simulation was conducted using the thermodynamic equilibrium calculation software MALT for Windows. The macroscale of thermodynamically stable compounds at an equilibrium state can be obtained using this software, which is applicable for predicting the mac...... hiện toàn bộ
Fireside Corrosion of Ni Base Self-Fluxing Alloy Coatings in WtE Plant: Effect of Flue-Gas and Metal TemperatureSpringer Science and Business Media LLC - Tập 87 - Trang 741-756 - 2017

Increase in the efficiency of energy recovery facilities is one of the challenges facing waste-to-energy (WtE) operators in the EU. To achieve this target, one option is optimization of the water/steam cycle to increase electrical efficiency. Nevertheless, increase in steam temperature in heat exchanger tubes results in increased fireside corrosion risks, particularly in superheater tubes, where s...... hiện toàn bộ
The oxidation behavior of an aligned Co-TaC eutectic alloySpringer Science and Business Media LLC - Tập 9 - Trang 225-257 - 1975
J. G. Smeggil
The oxidation behavior of the directionally aligned eutectic alloy, TaC-Co50B, has been examined between 600 and 1155°C. Parabolic oxidation behavior, isotropic in nature, is found to 800°C. Above 800°C, the oxidation behavior is no longer either parabolic or isotropic. The interaction between the Co matrix alloy and the TaC fibers adjacent to the oxidizing interface is reported as a function of ...... hiện toàn bộ
Kinetic Aspects of Ti2AlC MAX Phase OxidationSpringer Science and Business Media LLC - Tập 83 - Trang 351-366 - 2015
J. L. Smialek
The oxidation kinetics of a commercial Ti2AlC MAX phase compound were measured in 100 h isothermal thermogravimetric tests at 1,100, 1,200, and 1,300 °C. A significant amount of transient oxidation took place during the initial 5 min of heating due to the rapid growth of non-protective TiO2 scales. After correcting for this amount, shown as a knee in log–log plots, the mass gain was similar to tha...... hiện toàn bộ
