Abstract

The process for pickling in an acid bath containing an oxidant is distinguished in that, to increase the action of the pickling process, at least one peroxygenated compound of titanium or at least one element of the titanium family included in the product to be pickled is formed, with the metal ionised to a higher valency, the formation of the peroxygenated compound is monitored by measuring the redox potential and the quantity of oxidising agent is limited to conserve an oxy-reduction potential above the passivation potential of the metal product.
