Definitions

the subject of the invention is a bath and a process for the chemical conversion to zinc of metallic substrates, in particular those based on iron, zinc, aluminum and alloys of these metals.
chemical conversion is meant the surface transformations of metals, in particular in an acid medium, making it possible to modify their intrinsic properties and to confer on them new physical or physicochemical characteristics, in particular with a view to increase their corrosion resistance and promote the adhesion of film-forming coatings applied subsequently.
the Applicant Company has worked to improve the existing chemical conversion baths and had the merit of finding, after extensive research, that the implementation in a zinc phosphating bath of an effective amount of at least one compound comprising at least one fluorine atom chemically bonded to an atom phosphorus, preferably an effective amount of fluorophosphate ion, allowed to achieve the desired goal.
the abovementioned bath comprises from 1 to 10 g / 1, preferably from 2 to 7 g / 1, of zinc ion and from 1 to 10 g / 1, preferably from 2 to 7 g / 1, fluorophosphate ion.
the chemical conversion process in accordance with the invention consists in implementing the above-mentioned bath on the substrates to be treated by spraying or by quenching the substrates, the bath temperature being from 30 to 70 ° C., preferably from 50 to 55 °. C, the contact between bath and substrate being maintained for 5 to 200 seconds.
the concentrate according to the invention comprises the fluorophosphate ion, the zinc ion and the conventional constituents of the chemical conversion bath according to the invention in proportions such that this bath can be obtained by dilution with the appropriate quantity of water.
the invention also relates to a number of other provisions which will be discussed later and, in part culier, 1 - application of 1 fluorophospnaze ion in the chemical conversion baths.
a conventional chemical conversion bath to zinc is made to contain an amount of 1 to 10 g / l, preferably 2 to 7 g / l , of zinc ion and from 1 to 10 g / l, preferably from 2 to 7 g / l, of fluorophosphate ion.
the fluorophosphate anion can be brought in the form of alkaline monofluorophosphate or ammonium, in particular potassium K 2 PO 3 F, zinc monofluorophosphate ZnPO 3 F and others, or their mixtures.
the zinc ion can be brought in any suitable way and in particular in the form of its salts such as nitrate or phosphate or of its oxide.
the nickel ion can be brought in any suitable way and in particular in the form of its salts such as carbonate or nitrate.
the phosphate ion is present in a com taken between 3 and 20 gll, preferably between 3 and 15 g / l, and the nickel ion in an amount between 0.5 and 2 g / 1, preferably 0.5 to 1 g / 1.
the accelerator can be present in an amount between 40 and 150 mg / 1.
Conventional ions such as Fe, Ca, Mn can be present in an amount between 0 and 5 g / 1.
test pieces are treated either in a chemical dip bath conventionally used in industry, or in various baths according to the invention.
test pieces are immersed for 150 seconds in one of the above-mentioned chemical conversion baths.
Bath A This is a comparative example using a conventional bath, hereinafter designated by Bath A and the composition of which is as follows:
Bain B a bath in accordance with the invention, hereinafter called Bain B and the composition of which is as follows:
Bain D a bath according to the invention, hereinafter called Bain D and the composition of which is as follows:
Bath E This is an example using a bath in accordance with the invention, hereinafter called Bath E and the composition of which is as follows:
