Abstract

A process for producing, on aluminium and its alloys, matt black conversion coatings which bond well, are uniform and corrosion resistant. The metal surface is etched with an aqueous iron chloride solution, and then colored in an acidic, aqueous solution of ammonium molybdate and aluminium chloride and finally given an after-treatment with an aqueous, alkaline solution.
