In a process for applying a zinc coating to aluminium, suitable for creating a corrosion-resistant zinc-diffused surface layer on the aluminium by subsequent heating, the aluminium is dipped in a bath containing an aqueous solution of zinc fluoride, preferably essentially saturated, and at a temperature in the range of 20-70 DEG C. The bath is preferably maintained at pH 4-6. |
