摘要
Procedure for the pretreatment of metal surface, comprising the following steps: a) forming phosphating Layer, (b) and (c) laqueadoelectroforu00e9tico postenjuague Cathodic immersionIn which, in the Sub Phase (b), the postenluague takes c abo with an aqueous solution containing 0.001 g / l to 10 g / 1, one or more of the Lithium cations, Copper or silverAs well as a substance known as accelerator in the phosphating.The electrophoretic Coating catodicopor Immersion Stage c) may be carried out with a Cathodic electrophoretic Coating by Immersion with Conventional lead-acid or without lossesElectrophoretic unalaca cathodically precipitable by Immersion with modern, free of lead.In the stage fosfatiza) with an Acid Solution containing Zn, has a pH value of between 2.5 and 3.6 with at least one of the following: M - nitrobencensulfonato Accelerators, hydroxylamineIons nitrobenzoate, p-nitrophenol, hydrogen peroxide, Nitrile oxide ions, Organic n, nitroguanidine, nickel ions.In Step (b) the aqueous solution contains one or variosaceleradores phosphatization selected among: M - nitrobencensulfonato, hydroxylamine, ions, nitrobenzoate, p-nitrophenol,Hydrogen peroxide, ionesnitrito N - oxides, Organic, nitroguanidine, CHLORATE ions.
