PICKLING PROCESS IN AN ACID BATH OF METALLIC PRODUCTS CONTAINING TITANIUM OR AT LEAST ONE CHEMICAL ELEMENT OF THE TITANIUM FAMILY |
摘要 |
Pickling process in an acid bath containing an oxidant in order to enhance the pickling kinetics, wherein at least one peroxygenated derivative of titanium or at least of one element of the titanium family included in the product to be pickled is formed, the metal being ionized to a higher valency, the formation of the peroxygenated compound is controlled by measurement of the redox potential, and the quantity of oxidizing agent is limited so as to maintain an oxido-reduction potential lower than the passivation potential of the metallic product
