Abstract
Process for sheet titanium pickling followed by passivation. Pickling is carried out in an aqueous solution containing H.sub.2 SO.sub.4, HF and Fe.sup.3+ at .ltoreq.50.degree. C., continuously fed with an air flow, and with a stabilized H.sub.2 O.sub.2 quantity adjusted to the bath redox potential to be kept at -200 to 0 mV. Passivation is carried out in an aqueous bath containing 4 to 10 g/l HF, .ltoreq.1 g/l Fe.sup.3+, and not containing H.sub.2 SO.sub.4, with a redox potential kept at 500-600 mV by continuous feeding of stabilized H.sub.2 O.sub.2.
