Definitions

the present invention relates to a process for the electrodeposition of Zinc phosphate or zinc-calcium phosphate on metallic substrates of acidic Electrolyte.
the protection of metallic surfaces, especially the protection of iron and Steel surfaces, by phosphate-containing coatings has been known for a long time.
layer-forming phosphating is the use of alkali metal and / or ammonium orthophosphate solution for producing iron phosphate layers, in which the iron ion from the metallic to be coated Surface comes from.
Layer-forming phosphatings are those in which the metal surface using zinc or zinc / calcium phosphate solutions Zinc phosphate coatings or zinc-calcium phosphate coatings be formed.
Such phosphate coatings not only improve the corrosion protection of the Metal surfaces, but also increase liability for any later Coatings such.
zinc phosphate or Zinc / calcium phosphate layers the properties of the coated substrates in the cold forming such. B. improve the wire drawing. Especially such layers lead to a reduction of the friction coefficients.
European Patent Application EP 0 972 862 describes a method and a device for the electrodeposition of phosphate films Steel wires.
European patent application EP 0 987 350 also discloses Method for electroplating a phosphate coating on workpieces with great length.
the phosphate ions originate from the phosphoric acid H 3 PO 4 used , which dissociates to 3 H + and PO 4 3 , above all in the area of the diffusion layer.
the phosphate ions participate in zinc phosphate layer formation and are deprived of chemical equilibrium.
the protons originating from the acid remain in the reaction solution and lead to a shift in the equilibrium of the electrolyte.
iron originating from the substrate to be coated reacts due to the high hydrogen ion concentration in the course of the process with forming hydrophosphations to iron hypophosphates, which precipitates as so-called phosphating and leads to impurities in the bath, this reaction is usually not found in electrolytically guided process instead of.
the carbonates used dissociate to the metal cations and carbonate anions.
the carbonate anions can react with the protons originating from the phosphoric acid to carbonic acid, which according to Henry's law as a function of pressure and temperature as carbonic acid (H 2 CO 3 ) remain in solution or can outgas as carbon dioxide (CO 2 ).
zinc and / or calcium in the form of zinc and / or Calcium carbonate can be used.
the further addition of carbonates leads to quantitative extension of the electrolyte.
the galvanic phosphating can be started with a zinc-containing electrolyte to which calcium carbonate is added in the course of the process.
the deposited layer changes in the course of the process from a zinc phosphate layer (Zn 3 (PO 4 ) 2 ) to a zinc calcium phosphate layer (Zn 2 Ca (PO 4 ) 2 ).
This zinc-calcium phosphate layer has finer structures, which in cold forming processes such. B. the wire provides more favorable results.
