Definitions
- a sheet comprising a steel substrate having two faces each coated with a metal coating comprising zinc, magnesium and aluminum.
- Such sheets are more particularly intended for the manufacture of parts for the automotive industry, without being limited thereto.
- Metallic coatings essentially comprising zinc and aluminum in small proportion are traditionally used for their good protection against corrosion. These metallic coatings are now in competition with coatings including zinc, magnesium and aluminum.
- Such metallic coatings will be generally designated here under the term of zinc-aluminum-magnesium coatings or ZnAIMg.
- magnesium significantly increases the corrosion resistance of these coatings, which can make it possible to reduce their thickness or to increase the guarantee of protection against corrosion over time.
- Requirement US 2010/055344 describes a ZnAIMg coated steel sheet subjected to skin-pass steps, application of an oil, alkaline cleaning then application of a primer and a lacquer.
- Requirement JP 2003/013192 describes a steel sheet coated with ZnAIMg subjected to a skin-pass and then to the application of an oil.
- Requirement JP 2007/131906 describes a process for the preparation of sheets coated with a ZnAIMg coating and varnished comprising the steps consisting in supplying steel sheets coated with quenching by a ZnAIMg coating, subjecting them to polishing, oxidizing the surface by immersion in an alkaline solution, optionally immerse in a sulfuric acid solution containing Co and / or Ni ions, possibly chromating, then applying a varnish.
- Sheet metal coils with such surface coatings can sometimes remain in storage sheds for several months and must not see this surface deteriorate by the appearance of surface corrosion, before being shaped by the end user.
- no corrosion initiation should appear whatever the storage environment, even in the event of exposure to the sun and / or to a humid or even salty environment.
- Standard galvanized products that is to say whose coatings mainly consist of zinc and aluminum in low proportion, are also subject to these stresses and are coated with a protective oil which is generally sufficient to provide corrosion protection during storage.
- An object of the invention is to improve the temporary protection of sheets with ZnAIMg coatings.
- the invention firstly relates to a method according to claim 1.
- the method may also include the features of claims 2 to 14, taken in isolation or in combination.
- the application describes a sheet 1 having two faces 5 each coated with a metallic coating 7 comprising zinc, aluminum and magnesium and with a layer of oil, the metallic coatings 7 comprising between 0.1 and 20% by weight of aluminum and between 0.1 and 10% by weight of magnesium, the sheet being capable of being obtained by the process described below.
- Sheet 1 of the figure 1 comprises a steel substrate 3 covered on each of its two faces 5 by a metallic coating 7.
- the coatings 7 present on the two faces 5 are similar and only one will be described in detail below.
- the coating 7 generally has a thickness less than or equal to 25 ⁇ m and aims conventionally to protect the substrate 3 against corrosion.
- the coating 7 comprises zinc, aluminum and magnesium. It is particularly preferred that the coating 7 comprises between 0.1 and 10% by weight of magnesium and between 0.1 and 20% by weight of aluminum.
- the coating 7 comprises more than 0.3% by weight of magnesium or even between 0.3% and 4% by weight of magnesium and / or between 0.5 and 11% or even between 0.7 and 6% by weight of aluminum, or even between 1 and 6% by weight of aluminum.
- the Mg / Al mass ratio between the magnesium and the aluminum in the coating 7 is strictly less than or equal to 1, preferably strictly less than 1, or even strictly less than 0.9.
- the substrate 3 is in the form of a strip which is passed through a bath to deposit the coatings 7 by hot dipping.
- the bath is a bath of molten zinc containing magnesium and aluminum.
- the bath can also contain up to 0.3% by weight of each of the optional addition elements such as Si, Sb, Pb, Ti, Ca, Mn, Sn, La, Ce, Cr, Ni, Zr or Bi.
- the bath may finally contain residual elements from the feed ingots or resulting from the passage of the substrate 3 in the bath, such as iron at a content of up to 5% by weight and generally between 2 and 4% by weight .
- the substrate 3 is for example drained by means of nozzles projecting a gas on either side of the substrate 3.
- the coatings 7 are then allowed to cool in a controlled manner.
- the strip thus treated can then be subjected to a so-called skin-pass step which makes it possible to work harden it so as to erase the bearing of elasticity, to fix the mechanical characteristics and to confer on it a roughness suitable for subsequent operations such as sheet metal. must undergo.
- the means of adjusting the skin-pass operation is the rate of elongation which must be sufficient to achieve the objectives and minimum to maintain the capacity for subsequent deformation.
- the elongation rate is usually between 0.3 to 3%, and preferably between 0.3 and 2.2%.
- the outer surfaces 15 of the coverings 7 are then oiled to provide temporary protection.
- the oils used can conventionally be Quaker or Fuchs oils and the grammage of the layers of oils deposited on each external surface 15 is for example less than or equal to 5 g / m 2 .
- the layers of oil deposited were not shown on the figure 1 .
- the sheet 1 thus obtained can be wound before being cut, possibly shaped and assembled with other sheets 1 or other elements by users.
- XPS spectroscopy has also been used to measure the thickness of the magnesium oxide or magnesium hydroxide layers present on the exterior surfaces 15. It appears that these layers have a thickness of a few nm.
- the figures 2 and 3 illustrate respectively the spectra of the elements for the energy levels C1s (curve 17), O1s (curve 19), Mg1s (curve 21), Al2p (curve 23) and Zn2p3 (curve 25) during an analysis by spectroscopy XPS.
- the corresponding atomic percentages are plotted on the ordinate and the depth of analysis on the abscissa.
- the sample analyzed on the figure 2 corresponds to coatings 7 comprising 3.7% by weight of aluminum and 3% by weight of magnesium and subjected to a conventional skin-pass step with an elongation rate of 0.5% while the sample of the figure 3 has not been subjected to such a step.
- the thickness of the magnesium oxide or magnesium hydroxide layers is approximately 5 nm.
- ZnAIMg coated sheets have a low ability to be wetted with oil. This visually translates into a deposition of protective oil in the form of droplets while it is continuous or film-forming on conventional galvanized coatings.
- the inventors have also observed phenomena of dewetting of the deposited oil, so that certain zones are no longer covered with oils. Such an area is identified by the reference 41 on the figure 4 . Temporary protection is therefore heterogeneous.
- tarnishing phenomena linked or not to dewetting, may appear after a few weeks under certain storage conditions.
- This alteration step can be carried out by the means described in claim 1, such as, for example, the application of mechanical forces.
- Such mechanical forces are applied by a leveler, a brushing device or a blasting device.
- a leveler which is characterized by the application of plastic deformation by bending between rollers, can be adjusted to deform the sheet which passes through it enough to create cracks in the layers of magnesium oxide or hydroxide magnesium.
- the application of mechanical forces to the external surfaces 15 of the metallic coatings 7 can be combined with the application of an acid solution or the application of a degreasing, for example based on an alkaline solution, on the surfaces exterior 15.
- the acid solution has for example a pH of between 1 and 4, preferably between 1 and 3.5, preferably between 1 and 3, and more preferably between 1 and 2.
- This solution can comprise, for example hydrochloric acid , sulfuric acid or phosphoric acid.
- the duration of application of the acid solution can be between 0.2 s and 30 s, preferably between 0.2 s and 15 s, and more preferably between 0.5 s and 15 s, depending on the pH of the solution, when and how it is applied.
- This solution can be applied by immersion, sprinkling or any other system.
- the temperature of the solution can for example be room temperature or a whole other temperature and subsequent rinsing and drying steps can be used.
- the layers of magnesium oxide or magnesium hydroxide can be altered by applying an acid solution and without applying mechanical forces.
- the purpose of the possible degreasing step is to clean the external surfaces 15 and therefore to remove the traces of organic dirt, metallic particles and dust.
- this step does not modify the chemical nature of the exterior surfaces 15, with the exception of the alteration of a possible layer of surface aluminum oxide / hydroxide.
- the solution used for this degreasing step is non-oxidizing. No magnesium oxide or magnesium hydroxide is therefore formed on the outer surfaces during the degreasing step and more generally before the oil application step.
- a degreasing step it occurs before or after the step of applying the acid solution.
- the possible degreasing step and the step of applying the acid solution take place before a possible surface treatment step, that is to say a step making it possible to form layers (not shown) on the outer surfaces. ) improving the resistance to corrosion and / or the adhesion of other layers subsequently deposited on the external surfaces 15.
- Such a surface treatment step comprises the application to the exterior surfaces 15 of a surface treatment solution which reacts chemically with the exterior surfaces 15.
- this solution is a conversion solution and the layers formed are conversion layers.
- the conversion solution does not contain chromium. It can thus be a solution based on hexafluorotitanic or hexafluorozirconic acid.
- the mechanical forces will preferably be applied before the acid solution or when it is present on the external surfaces 15 to promote the action of the acid solution.
- the mechanical forces may be less intense.
- the step of applying the acid solution and the step of surface treatment are combined.
- the surface treatment solution is acidic.
- the pH can be strictly greater than 3, in particular if the surface treatment solution is applied at a temperature above 30 ° C.
- Table 1 Sample Alkaline degreasing Type of acid pH Acid exposure time in s Oil distribution observed with the naked eye 1 / / / / Discontinued 2 Gardoclean S5117 at 25g / l at a temperature of 55 ° C, applied for 15s, HCl 2 5 keep on going 3 / HCl 2 5 keep on going 4 / HCl 1 5 keep on going 5 / HCl 2 10 keep on going 6 / H2SO4 2 5 keep on going
- Samples 1 to 6 were also exposed to the ambient atmosphere for 12 weeks under the conditions described in standard VDA230-213 in order to assess their temporary protection.
- Sample 1 (curve 51 on the figure 5 ), which constitutes the reference, has a ⁇ L greater than 2, which is consistent with the distribution of the discontinuous oil observed visually.
- Samples 2 to 6 (curves 52 to 56 respectively on the figure 5 ) have a variation in luminescence of less than 2, therefore imperceptible to the naked eye.
