Abstract

In this study, we performed three surface modifications for AISI H13 steel to study their protective effects in 1023 K molten aluminum. Results showed that air oxidation can produce a thin film of Fe₂O₃ and little FeO, and the liquid-nitriding formed a surface of iron nitrides and oxides (Fe₂O₃ + Fe₃O₄). While liquid-nitriding with post-oxidation can form a surface of Fe₃O₄ and little Fe₂O₃ by oxidizing the nitrides into Fe₃O₄ on the liquid-nitriding samples. The Fe₃O₄ has low wettability and good chemical stability against molten aluminum, thus the corrosion behaviors of molten aluminum to the samples change from dissolution to oxidation.
