Al-enriched layer was formed on a magnesium substrate with use of casting. The magnesium melt was cast into a steel mould with an aluminium insert placed inside. Different conditions of the casting process were applied. The reaction between the molten magnesium and the aluminium piece during casting led to the formation of an Al-enriched surface layer on the magnesium substrate. The thickness of the layer was dependent on the casting conditions. In all fabricated layers the following phases were detected: a solid solution of Mg in Al, Al₃Mg₂, Mg₁₇Al₁₂₀ and a solid solution of Mg in Al. When the temperature of the melt and the mould was lower (variant 1 – 670^oC and 310^oC; variant 2 – 680^oC and 310^oC, respectively) the unreacted thin layer of aluminium was observed in the outer zone. Applying higher temperatures of the melt (685^oC) and the mould (325^oC) resulted in deep penetration of aluminium into the magnesium substrate. Areas enriched in aluminium were locally observed. The Al-enriched layers composed mainly of Mg-Al intermetallic phases have hardness from 187-256 HV0.1.
