Embodiment Construction

[0014] The following terms will be defined:

[0015] -Electrophoretic coating includes electrophoretic paint and electrophoretic paint deposition.

[0016] The invention relates to a panel for a vehicle comprising a steel sheet 1 having an outer surface 1a and an inner surface 1b. figure 1 An embodiment is shown in which the inner surface is coated with a coating 2 comprising 1.0 to 6.0% by weight of aluminum, 0.5 to 5.0% by weight of magnesium - preferably 1.0% to 5.0% by weight magnesium, the balance zinc and optional impurities and optional additional elements selected from Si, Sb, Pb, Ti, Ca, Mn, Sn, La, Ce, Cr, Zr or Bi , the weight content of each added element is less than 0.3% by weight, said steel plate being locally reinforced by at least one patch 3 bonded to said inner surface 1b. Preferably, the coating according to the invention is deposited on the inner and outer surfaces of the steel sheet.

[0017] Advantageously, the coating comprises 1.0% to 1.4% by weigh...

Abstract

The present invention relates to a panel for vehicle comprising a coated steel sheet locally reinforced, a method for preparing the panel and the use of the panel.

Description

technical field [0001] The invention relates to a panel for a vehicle comprising a coated steel sheet locally reinforced by patches. The invention is particularly applicable to the manufacture of automotive components. Background technique [0002] In view of reducing the weight of the vehicle, it is known to locally reinforce the steel plate by adding a patch. Therefore, the weight of the steel plate—that is, the thickness—is reduced and patches are locally added to achieve high strength. Steel sheets are usually coated with a metallic coating. The panels comprising the coated steel panels are then painted. In practice, however, it has been observed that known metallic coatings may be prone to the problem of paint delamination around the patch. [0003] In fact, water penetrates between the paint layer - such as electrophoretic coating - and the edge of the patch. Thus, the corrosion products formed under the paint layer cause the paint layer around the patch to be rel...
