Abstract:

FeCoNiCr high entropy alloy coatings were prepared by electrodeposition in sulfate system with citric acid and sodium citrate as the complexing agent. The effects of current density, bath temperature, and pH value on the composition, morphology, crystal structure and hardness of the coatings were studied. The results show that the prepared FeCoNiCr high entropy alloy coatings are amorphous and uniform. The optimized process parameters are: pH=2.5, temperature of 25 ℃, and current density of 25 A·dm^-2.
