Abstract

The inter-reaction mechanism of ingot iron with a molten aluminum is proposed and experimentally confirmed. It is shown that the three-layer coating is formed on the surface of ingot iron under the conditions of liquid-phase inter-reaction and consists of bund interlayers of Fe2Al5 and FeAl3 intermetallics and a heterogeneous structure based on solid solution and FeAl3. The micro-hardness of the structural components of the heterogeneous structure ranges from 1 (for Al (Fe)) to 6–9 GPA (for FeAl3+Al (Fe)). An increase in the exposure time during the heat treatment is accompanied by an increase of the quantity of structurally free FeAl3+Al (Fe) fragments in its composition.
