Al0.3CoCrNiFe High-Entropy Alloy

Resists molten zinc at 470 °C

This HEA maintains structural stability in molten zinc during hot-dip galvanizing and forms multiple diffusion layers with systematically revealed kinetics, making it a candidate for zinc-corrosion-resistant structural materials.

Advantages

Three diffusion layers form after 30 min of reaction with molten zinc at 470 °C

Al-rich region exists between the third intermediate layer and the HEA in the diffusion zone

Ni and Zn accumulate within cracks of the third intermediate layer
