| Abstract Scope |
Refractory High Entropy Alloys (RHEA) often suffer from poor oxidation resistance as a result of high growth kinetics and/or evaporation of refractory metal oxides. Recently, it was proven that some complex oxides such as (CrTaTi)O2 can protect RHEA in air at elevated temperatures. This paper gives an overview of protective properties of complex oxides including their advantages, drawbacks as well as future perspectives. The focus is on thermodynamic and kinetic aspects of complex oxide formation and growth, respectively. Finally, it is demonstrated that the novel concept of protection by complex oxides can be successfully applied on conventional high temperatures materials such as Ti-, Fe-, Co- and Ni-based alloys. |
