Electrolytic Aluminizing of Low-Carbon Steel in NaF-KF-AlF3 Melt

Article Preview

Abstract:

A multilayer intermetallic coating on low-carbon steel was obtained during aluminum electrodeposition in NaF-KF-AlF3 melt at 920 °C. The current density effect on morphology and intermetallic layer composition was investigated. Electrolytically aluminized steel samples represented a good oxidation resistance at 900 °C.
