Regulating TGO Nucleation and Growth of MCrAlX Coatings via Femtosecond Laser Remelting: The Role of Reactive Elements in the Oxidation Resistance

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser
