Definitions

the invention relates to a process for the production of phosphate coatings on surfaces which are formed from aluminum or its alloys and at least one of the materials steel or galvanized steel, in spraying or spray-dipping by means of phosphating solutions containing zinc, phosphate, fluoride ions and accelerators, and its use as Preparation of the surfaces for electrocoating.
the object of the invention is to provide a method for producing phosphate coatings on surfaces made of aluminum or its alloys and at least one of the Materials steel or galvanized steel are formed to provide, which does not have the aforementioned disadvantages, in particular leads to uniform phosphate coatings and can be carried out without effort in terms of the solution components and the process.
the aluminum materials to be treated by the method according to the invention include the pure metal and its Alloys. Pure aluminum, AlMg and AlMgSi kneading materials may be mentioned as examples. A detailed description of the aluminum materials can be found, for example, in the aluminum paperback, l4. Edition, Aluminum-Verlag, Düsseldorf, l983.
the term steel is understood to mean unalloyed to low-alloy steel, as it e.g. in the form of sheets for body construction.
galvanized steel includes e.g. Galvanized and hot-dip galvanized and refers to zinc and zinc alloys, e.g. ZnNi, ZnFe, ZnAl.
the method according to the invention is used in spraying and splash immersion.
the spraying time must be at least as long as is necessary for an at least largely closed phosphate layer formation on the aluminum. This usually takes at least 60 seconds.
the metal surfaces to be treated must be free from disruptive deposits of oils, lubricants, oxides and the like, which can impair proper layer formation.
the surfaces are cleaned in a suitable manner.
the surface is preferably activated with an activating agent known per se, for example an aqueous suspension containing titanium phosphate, before the phosphate coating is produced.
the activating agent can be used in the cleaning bath or as a separate process step.
the required fluoride concentration measured with the fluoride-sensitive electrode corresponds approximately to the proportion of dissociated fluoride (F ⁇ ) present in the phosphating solution.
F (el) value 80 to 220 mg / l at the usual bath pH values of the low zinc phosphating baths
about 0.4 to 0.9 g / l NH4HF2 or equivalent amounts of other single fluoride containing must Salts are added.
the bath is preferably supplemented by adding enough simple fluoride-containing salt to the bath until the desired measured value of F (el) is reached. At least part of the fluoride is added as single fluoride.
the phosphating solutions can also contain complex fluoride, e.g. of boron or silicon, contained in the amounts customary in phosphating technology. Any fluoride released by dissociation is also detected by the fluoride-sensitive electrode and is therefore contained in the setpoint to be set.
complex fluoride e.g. of boron or silicon
the correct setting of the free acid (FS) in the phosphating solution is essential for the type of formation of the phosphate coating. Basically, it can be said that in the phosphating solutions used in the process according to the invention the free acid is significantly higher than in the corresponding fluoride-free phosphating solutions. If one tries, after adding fluoride, to maintain the usual value for the free acid before the addition, the zinc concentration decreases rapidly and the quality of the layers produced deteriorates.
the low value in brackets applies to low concentrations of P2O5, the higher value for higher concentrations in the phosphating solution.
the correction element K takes into account the influence of the measured fluoride activity (F (el)) on the optimal free acid content.
F (el) is used in the dimension (mg / l).
F (el) is used in the dimension (mg / l).
FS free acidity
10 ml bath sample with approx. 100 ml completely deionized water and titrated with 0.1 l NaOH against the change of dimethyl yellow to a weak yellow color, which corresponds to a pH value of 4.25.
FS is equal in number to the ml of sodium hydroxide solution used.
the substances generally used in phosphating technology can be used as accelerators. It is particularly advantageous to bring the surface into contact with an aqueous phosphating solution which, as accelerators, contains chlorate, bromate, nitrate, nitrite, Peroxide and / or organic nitro compounds, such as meta-nitrobenzenesulfonate contains. They are dosed in the usual quantities.
Another expedient embodiment of the invention provides for the phosphate coatings to be produced by bringing the surface into contact with an aqueous phosphating solution which additionally contains one or more cations from the group Ni, Mn, Mg, Ca, preferably in amounts of 0.1 up to 1.5 g / l. Some of these cations are built into the phosphate layer and, under special conditions, can lead to an improvement in the layer quality.
the phosphating solutions can also contain other additives known in phosphating technology for modifying the procedure and the layer properties.
additives known in phosphating technology for modifying the procedure and the layer properties. Examples include: surfactants, polyhydroxycarboxylic acids, polyphosphates, ammonium, alkali, copper, cobalt ions and indifferent anions such as chloride and sulfate.
the phosphating bath temperature is usually chosen between 40 and 60 ° C and the spraying time between 1 and 3 min.
the phosphate layers produced by the process according to the invention have a weight per unit area of approximately 1 to 5 g / m 2 and can be used well in all areas in which phosphate coatings are used.
a particularly advantageous application is the preparation of the metal surfaces for painting, in particular electrocoating.
