| Abstract Scope |
Despite excellent high-temperature properties of refractory high-entropy alloys (RHEAs), they are vulnerable to corrosion and surface abrasion, which compromise the material integrity and confine their broader application. To tackle this challenge, instead of coating a protective layer or tuning their composition, a novel strategy is implemented, specifically by introducing Laser-Induced Periodic Surface Structure (LIPSS). LIPSS is a rapid and cost-effective technique that uses laser processing to create nanoscale patterns on the material's surface, leading to enhanced surface properties. This study is among the first to explore the potential of LIPSS to create surface nanopatterns and a gradient nanostructure by inducing microstructural changes, potentially improving oxidation resistance, wear resistance, and surface hardness in RHEA, paving the way for more durable, high-performance materials in demanding environments. |
