Abstract

Aluminium metal or alloy articles are treated with an aqueous etching solution containing an alkali metal hydroxide, a sequestering agent and such an amount of a stable thickener that the solution has a viscosity of at least 17 Stein Hall seconds at 80 DEG C. The solution preferably contains, by weight of water, 10-30% NaOH, 1-6% sequestering agent e.g. sodium (boro) gluconate or triethanolamine gluconate, and 0.5-5% thickener e.g. derivatives of starch or cellulose, alginates or polyvinyl alcohol. Examples of derivatives are carboxymethyl or hydroxyethyl starch or cellulose, hydroxypropyl starch or starch propyl sulphonate. Other examples of sequestering agents are glucoheptonic, citric, saccharic, mucic or tartaric acids or salts thereof, E.D.T.A. and sorbitol. The solution may also contain 0.1-0.5% free alkanolamine in which the or each alkanol contains up to 4 carbon atoms such as triethanolamine. The treatment may be to dissolve off surface film, to deep-etch e.g. taper a rod, or to produce a recesses pattern on the article surface.
