This work aims to study the effect of elemental sluggish diffusion on the oxidation resistance
of Al 2 O 3-forming high-entropy alloys (HEAs). We compare the oxidation behavior of an …

We present a comparative study on oxidation behavior and failure mechanisms of
conventional NiCoCrAl alloys doped with Y and Hf (CNA) and in-situ composite AlCoCrFeNi …

Equimolar AlCoCrFeNi high entropy alloy (HEA) with a coherent dual-phase structure
commonly exhibits good strength at high temperatures. Regretfully, the poor oxidation …

We report an in-situ oxide-dispersion-strengthened AlCoCrFeNiY high-entropy alloy
composite coating (ODS-HEA composite coating) with exceptional oxidation and spallation …

In this study, the oxidation behavior of AlCoCrFeNi high-entropy alloy powder at 900-1100°
C was first investigated and reported. The triple-phase nanostructure in the early oxidation …

Dual-phase PtAl coatings with Ru modification (RPT coatings) have been prepared on a
nickel-based superalloy by electroplating Ru/Pt layers before the chemical vapor deposition …

The NiCoCrAlY alloy with uniform yttrium distribution was fabricated via powder milling and
spark plasma sintering. After powder milling, yttrium was uniformly distributed in the alloy in …

Surface rumpling is detrimental to high temperature protective coatings as it shortens their
lifetime and leads to adhesion losses and unexpected corrosion degradation. The driving …

The effect of grain size and porosity of a NiCoCrAlY coating fabricated by high-velocity air
fuel on the isothermal oxidation behavior is studied. To understand this effect, the …

A new type of Y-Hf co-doped Al 1.1 CoCr 0.8 FeNi high-entropy alloy (HEA) with a coherent
nanostructure and its oxidation behavior at 1200° C are reported in this work. The …
