A process is described for treating metal surfaces with a composition comprising an oxidizer, an acid, a corrosion inhibitor, a source of halide ions, a source of adhesion enhancing ions selected from the group consisting of molybdates, tungstates, tantalates, niobates, vanadates and mixtures thereof and optionally a water soluble polymer in order to increase the adhesion of polymeric materials to the metal surface.
