چکیده
An AlCoCrFeNiY high-entropy alloy coating was prepared using air plasma spray. The cyclic oxidation behavior of the investigated and compared with that a conventional NiCoCrAlY coating. It is demonstrated exhibits much stronger resistance to spallation than when they are thermally cycled between room temperature 1050-1150 °C. difference attributed lower growth rate oxide scale on as result its significantly higher activation energy absence spinel.

متن کاملHigh-temperature degradation of plasma sprayed thermal barrier coating systems
Thermal barrier coating systems (TBCs) are used in gas turbines to prevent high-temperature degradation of metallic materials in the combustor and turbine. One of the main concerns regarding TBCs is poor reliability, and accurate life prediction models are necessary in order to fully utilise the beneficial effects of TBCs. This research project aims at developing deeper understanding of the deg...

Nickel base superalloy alloys are used in the manufacture of gas turbine engine components, which in use are exposed to high temperatures and corrosive environments. The platinum aluminide coatings described here have been developed to protect nickel base superalloy alloys from oxidation. In this study, the effect of cyclic oxidation, platinum layer thickness and aluminizing process on beha...
متن کاملGraphene Oxidation Barrier Coating
Since its experimental isolation in 2004, graphene has shown some outstanding properties. We propose that graphene can be used as an oxidation barrier coating and its oxidation resistance weakens at the graphene grain boundaries. Copper is a superior conductor but is easily oxidized in air at room temperature or higher. Using graphene as a coating material may reduce the cost of protecting agai...
