AlCrFeNi is proposed as a protective coating to address the limitations of bulk HEAs, with its properties optimized through atmospheric plasma spraying (APS). As the properties of powders are essential for APS, their characteristics were analyzed. The gas-atomized AlCrFeNi powders exhibit an ideal high-entropy state with spherical morphology, uniform elemental distribution, and a single BCC phase due to rapid cooling and sluggish diffusion. After heat treatment above 900 °C, phase separation was observed, forming AlNi-rich phases of BCC/B2 and FeCr-rich phases of BCC/A2. Corrosion tests indicated that as-atomized powders have superior corrosion resistance compared to heat-treated powders and SS316. However, the precipitation of AlNi phases caused micro-galvanic corrosion, compromising the material's performance. APS-deposited coatings from gas-atomized powders formed a dense and uniform-layered structure, maintaining excellent corrosion resistance. Nevertheless, high-temperature exposure induced phase separation, resulting in micro-galvanic corrosion.

Since this method uses ultrasound as the source, it can be analyzed in a lab frame without the use of a large synchrotron radiation facility, and it can be used to analyze optically opaque materials. The proposed electrophoretic dynamic ultrasound scattering method uses a source with a wavelength longer than that of visible light, making it applicable to a wide range of particle sizes, including nanoparticles, submicron particles, and micron-sized particles.
