Influence of micro arc oxidation on high temperature oxidation resistance of AlTiCrVZr refractory high entropy alloy

, 2021
In order to inhibit the volatilization of V and improve the high temperature oxidation resistance of AlTiCrVZr refractory high entropy alloy, the micro arc oxidation (MAO) coatings were prepared on AlTiCrVZr high entropy alloy in three different ...

High-temperature oxidation behaviour of CoCrNi medium-entropy alloy

Corrosion Science, 2020
The high-temperature oxidation behaviour of CoCrNi was investigated over different exposure times (6, 12, 24, and 48 h) at 900–1100 °C. The initial phase identification indicated that the tendency of oxide formation at 1100 °C was different after each ...

High temperature oxidation of Al4C3

Corrosion Science, 2020
Abstract Currently, high temperature corrosion resistant materials rely on the formation of an external surface oxide layer. This work is the first step in exploring an alternative coating concept in which one continuous phase in a two phase carbide–metallic binder coating system, preferentially oxidises internally within the composite.

Effect of Sn addition on the high-temperature oxidation behavior of high Nb-containing TiAl alloys

, 2020
The effect of Sn addition on the oxidation behavior of high-Nb containing TiAl alloys was investigated with isothermal oxidation tests conducted in static air at 1000 °C. Sn addition can improve the high-temperature oxidation resistance of TiAl alloys by

High-temperature reactions of phenyl oxidation

Symposium (International) on Combustion, 1994
The reactions of phenyl radicals with molecular and atomic oxygen have been studied in the temperature range 900–1800 K behind reflected shocks. The total pressure ranged from 1.3 to 2.5 bar. Phenyl radicals were generated by the fast thermal decomposition of nitroso- or iodobenzene.

High temperature oxidation of Co-Mn alloys

Corrosion Science, 1979
Abstract The oxidation of cobalt-manganese alloys in the range 0–45 wt%Mn corresponding to the stability of the α-phase of cobalt has been studied in the range 750–950°C as an example of binary alloys producing solid solution scales. The alloys oxidize according to a parabolic rate law with a rate constant intermediate between those of the pure ...

High-pressure and high-temperature studies on oxide garnets

Physical Review B, 1996
We report high-pressure and high-temperature studies on a series of oxide garnets of chemical composition ${A}_{3}{B}_{2}{C}_{3}{\mathrm{O}}_{12}$. The members of this family investigated are gadolinium scandium gallium garnet (GSGG), gadolinium gallium garnet (GGG), and yttrium aluminum garnet (YAG).
