Definitions
- the present invention relates to a sheet comprising a substrate of which at least one face is coated with a metal coating comprising Al and Mg, the remainder of the metal coating being Zn, unavoidable impurities and optionally one or more additional elements. selected from Si, Ti, Ca, Mn, La, Ce and Bi, the weight content of each additional element in the metal coating being less than 0.3%.
- Galvanized metal coatings consisting essentially of zinc and 0.1 to 0.4% by weight of aluminum are traditionally used for their good protection against corrosion.
- Such metal coatings will generally be referred to herein as zinc-aluminum-magnesium or ZnAIMg coatings.
- magnesium significantly increases the corrosion resistance of steels coated with a metal coating, which can reduce the thickness of the metal coating or increase the guarantee of protection against corrosion over time at constant thickness .
- These sheets coated with a ZnAIMg coating are for example intended for the automotive field, household electrical appliance or construction.
- JP2010255084 it is known from JP2010255084 to improve the resistance to cracking by adding from 0.005 to 0.2% by weight of nickel to a metal coating comprising moreover 1 to 10% by weight of aluminum and 0.2 to 1% by weight. magnesium weight.
- the Nickel thus added has the characteristic of being
- Nickel migration at the steel-metal interface is difficult to perform and introduces additional manufacturing constraints.
- the present invention aims to overcome the aforementioned problems by proposing a ZnAIMg sheet whose metal coating crack less on severe folds, while retaining the advantages of ZnAIMg coating in terms of corrosion resistance.
- the invention firstly relates to a method for producing a prepainted sheet comprising at least the steps of:
- a metal coating on at least one face by quenching the substrate in a bath consisting of 4.4% to 5.6% by weight of aluminum and 0.3% to 0.56% by weight of magnesium, the remainder of the bath being exclusively zinc, unavoidable impurities related to the process and optionally one or more additional elements selected from the group consisting of Si, Ti, Ca, Mn, La, Ce and Bi, the content by weight of each additional element in the metal coating being less than 0.3%, the presence of nickel being excluded,
- the method according to the invention may also comprise the following optional characteristics, taken alone or in combination:
- the bath comprises from 4.75 to 5.25% by weight of aluminum, the bath comprises from 0.44 to 0.56% by weight of magnesium,
- the bath is at a temperature of between 370 ° C. and 470 ° C.
- the solidification of the metal coating is carried out at a cooling rate of the metal coating between the beginning of the solidification and the end of the solidification greater than or equal to 15 ° C / s,
- the cooling rate is between 15 and 35 ° C / s
- the surface preparation comprises a step chosen from a rinsing, a degreasing and a conversion treatment,
- the degreasing is carried out at a pH of between 12 and 13,
- the conversion treatment is based on hexafluorotitanic acid
- the painting of the metallic coating is carried out by means of a paint comprising at least one polymer chosen from the group consisting of melamine-crosslinked polyesters, isocyanate-crosslinked polyesters, polyurethanes and halogenated derivatives of vinyl polymers, exclusion of cataphoretic paints.
- the solution to the technical problem consists in combining a paint film and a metal coating having a particular composition. Surprisingly, it has been found by the inventors that this combination has an action synergy so that the ZnAIMg coating according to the invention has fewer cracks on the severe folds when it is covered with a film of paint than when he is naked.
- a second subject of the invention consists of a pre-painted sheet comprising a steel substrate of which at least one face is coated with a metal coating consisting of 4.4% to 5.6% by weight of aluminum and 0.3% 0.56% by weight of magnesium, the remainder of the metal coating being exclusively zinc, unavoidable impurities related to the process and optionally one or more additional elements selected from the group consisting of Si, Ti, Ca, Mn, La, Ce and Bi, the weight content of each additional element in the metal coating being less than 0.3%, the presence of nickel in the metal coating being excluded, the metal coating being covered with at least one paint film.
- the sheet according to the invention may also comprise the following optional characteristics, taken alone or in combination:
- the metal coating comprises from 4.75 to 5.25% by weight of aluminum
- the metal coating comprises from 0.44 to 0.56% by weight of magnesium
- the metal coating does not include any additional element
- the paint film comprises at least one polymer chosen from the group consisting of melamine-crosslinked polyesters, isocyanate-crosslinked polyesters, polyurethanes and halogenated derivatives of vinyl polymers, with the exception of cataphoretic paints,
- a conversion layer comprising titanium is located at the interface between the metal coating and the paint film.
- the sheet comprises a steel substrate coated on at least one of its faces with a metal coating, itself covered with at least one paint film.
- the metal coating generally has a thickness of less than or equal to 25 ⁇ m and is intended to protect the substrate against corrosion.
- the metal coating consists of aluminum and magnesium, the remainder of the metal coating being exclusively zinc, unavoidable impurities related to the deposition process of the metal coating and optionally one or more additional elements selected from Si, Ti, Ca, Mn, La, Ce and Bi, the weight content of each additional element in the metal coating being less than 0.3%, the presence of nickel being excluded.
- the weight content of aluminum of the metal coating is between 4.4 and 5.6%. This range of aluminum weight content promotes the formation of Zn / Al binary eutectic in the microstructure of the metal coating. This eutectic is particularly ductile and promotes the obtaining of a flexible metal coating.
- the content by weight of aluminum is between 4.75 and
- the content by weight of aluminum is measured without taking into account the aluminum-rich intermetallic located at the interface substrate-metal coating. Such a measurement can for example be carried out by glow discharge spectrometry. A measurement by chemical dissolution would lead to the simultaneous dissolution of the metal coating and intermetallic and give an over-estimated aluminum content by weight of the order of 0.05 to 0.5% depending on the thickness of the metal coating.
- the weight content of magnesium metal coating is between 0.3 and 0.56%. Below 0.3%, the improvement in the resistance to corrosion provided by magnesium is no longer sufficient. Above 0.56%, the synergistic action of the paint film and the metal coating according to the invention is no longer observed.
- the weight content of magnesium is between 0.44 and 0.56%, which constitutes the best compromise in terms of corrosion resistance and flexibility.
- the unavoidable impurities come from the feed ingots of the molten zinc bath or result from the passage of the substrate in the bath.
- the most common unavoidable impurity resulting from the passage of the substrate in the bath is iron which may be present at a content of up to 0.8% by weight of the metal coating, generally less than or equal to 0.4% and generally between 0.1 and 0.4% by weight.
- the unavoidable impurities from the ingots are generally lead (Pb), present at a content of less than 0.01% by weight, Cadmium (Cd), present at a content of less than 0.005% by weight and tin (Sn), present at a content of less than 0.001% by weight. It should be noted here that nickel is not an unavoidable impurity related to the galvanizing process.
- the various additional elements may make it possible, inter alia, to improve the ductility or adhesion of the metal coating to the substrate.
- the metal coating does not include nickel as an additional element, nickel having the drawbacks mentioned above.
- the metal coating does not include any additional elements. This simplifies the management of the galvanizing bath and minimizes the number of phases formed in the metal coating.
- the sheet finally includes a paint film.
- the paint films are generally based on polymers and comprise at least one layer of paint.
- they comprise at least one polymer selected from the group consisting of melamine-crosslinked polyesters, isocyanate-crosslinked polyesters, polyurethanes and halogenated derivatives of vinyl polymers, with the exception of cataphoretic paints.
- These polymers have the characteristic of being particularly flexible, which promotes the synergistic action of the paint film and the metal coating.
- the paint film may be formed for example of two layers of successive paints, namely a primer layer and a topcoat which is generally the case for producing the film applied to the upper face of the sheet, or a layer of single paint, which is generally the case for making the film applied to the lower face of the sheet. Other numbers of layers may be used in certain variants.
- the paint films typically have thicknesses of between 1 and 200 ⁇ m.
- the interface between the metal coating and the paint film includes one or more characteristics to be selected from an alteration of the naturally occurring aluminum oxide / hydroxide layer on the surface metal coating, an alteration of the magnesium oxide / hydroxide layer naturally occurring on the surface of the metal coating and a conversion layer characterized by its chromium layer weight (in case of chromate conversion treatment) or by its weight of titanium layer (in case of conversion treatment without chromium).
- the installation used may comprise a single line or, for example, two different lines for producing respectively the metal coatings and the painting.
- two different lines may be located on the same site or on separate sites. In the remainder of the description, for example, a variant in which two distinct lines are used is considered.
- a steel substrate obtained for example by hot rolling then cold.
- the substrate is in the form of a strip which is passed through a bath to deposit the metal coating by hot quenching.
- the bath is a molten zinc bath containing 4.4 to 5.6% by weight of aluminum and 0.3 to 0.56% by weight of magnesium.
- the bath may also contain unavoidable process-related impurities, such as impurities from the bath feed ingots, and / or one or more additional members selected from the group consisting of Si, Ti, Ca, Mn, La, Ce and Bi, the weight content of each additional element in the metal coating being less than 0.3%, the presence of nickel being excluded.
- the most common unavoidable impurity resulting from the passage of the substrate in the bath is iron which may be present at a content of up to 0.8% by weight, generally less than or equal to 0.4% and generally between 0.1 and 0.4% by weight.
- the unavoidable impurities from the ingots are generally lead (Pb), present at a content of less than 0.01% by weight, Cadmium (Cd), present at a content of less than 0.005% by weight and tin (Sn), present at a content of less than 0.001% by weight.
- Pb lead
- Sn tin
- nickel is not an unavoidable impurity related to the galvanizing process.
- the bath has a temperature between 350 ° C and 510 ° C, preferably between 370 ° C and 470 ° C.
- the substrate is for example spun by means of nozzles throwing a gas on either side of the substrate, so as to adjust the thickness of the coatings.
- the wringing gas does not comprise particles or solutions such as, for example, those comprising a magnesium phosphate and / or a magnesium silicate.
- a brushing may be performed to remove the coating deposited on one side so that only one side of the sheet will ultimately be coated.
- the coatings are then allowed to cool in a controlled manner to solidify.
- the controlled cooling of the or each coating is carried out by means of a cooling box or any other suitable means and is provided at a speed preferably between 2 ° C / sec, corresponding approximately to a natural convection, and 35 ° C / sec between the onset of solidification (ie, when the coating reaches a temperature just below that of the liquidus) and the end of solidification (that is, when the coating reaches the temperature solidus). It was found that cooling rates above 35 ° C / sec did not improve the results further.
- the cooling is provided at a speed greater than or equal to 15 ° C / sec which contributes to refining the microstructure of the metal coating and thus to avoid the formation on the metal coating of a visible flowering to the naked eye and which remains apparent after painting. More preferably, the cooling rate is between 15 and 35 ° C / sec.
- the strip thus treated can then be subjected to a so-called skin-pass step which allows it to be hardened so as to erase the level of elasticity, to fix the mechanical characteristics and to give it a roughness adapted to the stamping operations and the quality of the painted surface that one wishes to obtain.
- the band may optionally be wound before being sent to a prelacing line.
- the outer surfaces of the coatings are subjected to a surface preparation step.
- a preparation comprises at least one step chosen from a rinsing, a degreasing and a conversion treatment.
- Rinsing is intended to remove loose dirt, possible residues of conversion solutions, soaps eventually formed and present a clean and reactive surface.
- degreasing is to clean the surface by removing all traces of organic dirt, metal particles and dust from the surface. This step also makes it possible to alter the oxide / aluminum hydroxide and magnesium oxide / hydroxide layers that may be present on the surface of the metal coating, without however unduly modifying the chemical nature of the surface. Such tampering improves the quality of the metal coating / paint film interface which improves the corrosion resistance and adhesion of the paint film.
- the degreasing is carried out in an alkaline medium. More preferably, the pH of the degreasing solution is between 12 and 13.
- the conversion treatment step comprises applying to the metal coating a conversion solution that chemically reacts with the surface and thereby forming conversion layers on the metal coating. These conversion coats increase the adhesion of the paint and the corrosion resistance.
- the conversion treatment is an acid solution not containing chromium. More preferably, the conversion treatment is based on hexafluorotitanic acid or hexafluorozirconic acid.
- the possible stages of degreasing and conversion treatment may include other sub-stages of rinsing, drying ...
- the surface preparation may also include a step of altering the magnesium oxide and magnesium hydroxide layers formed on the surface of the metal coating.
- This alteration can in particular, the application of an acidic solution before application of the conversion solution, or the application of an acidified conversion solution at a pH of between 1 and 5 or else the application of mechanical stresses on the area.
- the painting is carried out by deposition of paint layers by means of, for example, roller coaters.
- Each deposit of a paint layer is generally followed by baking in an oven so as to crosslink the paint and / or evaporate the possible solvents and thus obtain a dry film.
- prepainted sheet The sheet thus obtained, called prepainted sheet, can be rewound before being cut, possibly shaped and assembled with other sheets or other elements by users.
- the propensity to crack of a ZnAIMg sheet, prepainted or not, is evaluated as follows:
- a T-bend fold is made on a specimen of a sheet according to the EN 13523-7 standard of April 2001,
- T-bend 2T and 3T folds were then made on both the bare sheets and those coated and analyzed.
- T-bend 2T and 3T plies were also on bare or coated sheet including other types of ZnAIMg coating.
- Tables 1 and 2 summarize the results obtained, respectively ZnAIMg bare sheets and zinc coated ZnAIMg sheets. The comparison of the 1 and 2 show that, very surprisingly, the cracks in the ZnAIMa coating thickness according to the invention are significantly less numerous.
