Definitions

  • the present invention relates to a steel sheet coated with a metallic coating.
  • the invention is particularly well suited for the manufacture of automotive vehicles.
  • Zinc-based coatings are generally used because they allows for a protection against corrosion thanks to barrier protection and cathodic protection.
  • the barrier effect is obtained by the application of a metallic coating on steel surface.
  • metallic coatings prevent the contact between steel and corrosive atmosphere.
  • the barrier effect is independent from the nature of coating and substrate.
  • sacrificial cathodic protection is based on the fact that zinc is a metal less noble that steel. Thus, if corrosion occurs, zinc is consumed preferentially to steel. Cathodic protection is essential in areas where steel is directly exposed to corrosive atmosphere, like cut edges where surrounding zinc will be consumed before steel.
  • the coating comprises, in terms of weight %, Al: at least 45% and no greater than 70%, Mg: at least 1% and less than 5%, Si: at least 0.5% and less than 3%, with the remainder Zn and unavoidable impurities, wherein the Al/Zn ratio is 0.89-2.75 and the plating layer contains a scaly Mg 2 Si phase.
  • Mg 2 Si phases scaly or bulky
  • Mg 2 Si phases are complex. Indeed, it depends on the size and on the ratio of the short diameter mean size with respect to the long diameter of Mg 2 Si phases, as observed with a 5° polished cross-section. The size is affected most predominantly by the cooling rate after hot-dip plating.
  • the fabrication of Mg 2 Si phases also depends on the quantity of Mg and Si.
  • Mg 2 Si phases can be difficult to obtain because of these specifics criteria. Therefore, there is a risk that the desired Mg 2 Si phase is not obtained.
  • the purpose of the invention is to provide a coated steel sheet easy to form having a reinforced protection against corrosion, i.e. a sacrificial cathodic protection in addition to barrier protection, before and after the forming.
  • electrochemical potential has to be at least 50 mV more negative than the potential of steel, i.e. a maximum potential of ⁇ 0.78V with respect to a saturated calomel electrode (SCE). It is preferable not to decrease the potential at a value of ⁇ 1.4V/SCE, even ⁇ 1.25V/SCE which would involve a fast consumption and would finally decrease the period of protection of steel.
  • a steel sheet coated with a metallic coating comprising from 2.0 to 24.0% by weight of zinc, from 7.1 to 12.0% by weight of silicon, optionally from 1.1 to 8.0% by weight of magnesium, and optionally additional elements chosen from Pb, Ni, Zr, or Hf, the content by weight of each additional element being less than 0.3% by weight, the balance being aluminum and optionally unavoidable impurities and residuals elements, wherein the ratio Al/Zn is above 2.9.
  • the invention also provides parts made from the steel sheet coated with the metallic.
  • the invention further provides a coated part for the manufacture of an automotive.
  • FIG. 1 illustrates one corrosion cycle corresponding to 168 hours of the norm VDA 233-102.
  • any steel can be advantageously used in the scope of the invention.

  • the part is obtained by cold-stamping.
  • the coated steel sheet is cut to obtain a blank and then cold-stamped in order to obtain a part.
  • the part coated is obtained by a press hardening process including the hot-forming.
  • this method comprises the following steps:
  • a thermal treatment is applied to the blank in a furnace under non protective atmosphere at an austenitization temperature Tm usually between 840 and 950° C., preferably 880 to 930° C.
  • Tm austenitization temperature
  • said blank is maintained during a dwell time tm between 1 to 12 minutes, preferably between 3 to 9 minutes.
  • the coating forms an alloy layer having a high resistance to corrosion, abrasion, wear and fatigue.
  • the blank is then transferred to a hot-forming tool and hot-formed at a temperature between 600 and 830° C.
  • the hot-forming comprises the hot-stamping and the roll-forming.
  • the blank is hot-stamped.
  • the part is then cooled in the hot-forming tool or after the transfer to a specific cooling tool.
  • the cooling rate is controlled depending on the steel composition, in such a way that the final microstructure after the hot-forming comprises mostly martensite, preferably contains martensite, or martensite and bainite, or is made of at least 75% of equiaxed ferrite, from 5 to 20% of martensite and bainite in amount less than or equal to 10%.
  • a coated part according to the invention can thus obtained by cold or hot forming but also by any suitable combination of cold-stamping and hot-forming.
  • the part is a press hardened steel part having a variable thickness
  • the press hardened steel part of the invention can have a thickness which is not uniform but which can vary. Indeed, it is possible to achieve the desired mechanical resistance level in the zones which are the most subjected to external stresses, and to save weight in the other zones of the press hardened part, thus contributing to the vehicle weight reduction.
  • the parts with non-uniform thickness can be produced by continuous flexible rolling, i.e. by a process wherein the sheet thickness obtained after rolling is variable in the rolling direction, in relationship with the load which has been applied through the rollers to the sheet during the rolling process.
  • the part can be a front rail, a seat cross member, a side sill member, a dash panel cross member, a front floor reinforcement, a rear floor cross member, a rear rail, a B-pillar, a door ring or a shotgun.
  • the part is dipped in an e-coating bath.
  • the thickness of the phosphate layer is between 1 and 2 ⁇ m and the thickness of the e-coating layer is between 15 and 25 ⁇ m, preferably less than or equal to 20 ⁇ m.
  • the cataphoresis layer ensures an additional protection against corrosion.
  • paint layers can be deposited, for example, a primer coat of paint, a basecoat layer and a top coat layer.
  • the part Before applying the e-coating on the part, the part is previously degreased and phosphated so as to ensure the adhesion of the cataphoresis.
  • steel sheets used are 22MnB5.
  • All coatings were deposited by hot-dip galvanization process. All coatings have a thickness of 15 ⁇ m.
