Description

A method for the manufacture of a coated steel sheet
The present invention relates to a method for the manufacture of a coated steel sheet. The invention is particularly well suited for the manufacture of automotive vehicles.
Zinc based coatings are generally used because they allow 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. Thus, the metallic coating prevents the contact between steel and corrosive atmosphere. The barrier effect is independent from the nature of coating and substrate. On the contrary, sacrificial cathodic protection is based on the fact that zinc which is more active metal as compared to 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.
However, when heating steps are performed on such zinc coated steel sheets, for example hot press hardening or welding, cracks are observed in steel which spread from the steel/coating interface. Indeed, occasionally, there is a reduction of metal mechanical properties due to the presence of cracks in coated steel sheet after the above operation. These cracks appear with the following conditions: high temperature; contact with a liquid metal having a low melting point (such as zinc) in addition to presence of an external stress; heterogeneous diffusion of molten metal with substrate grain and grain boundaries. The designation for such phenomenon is known as liquid metal embrittlement (LME) and also called liquid metal assisted cracking (LMAC).
Thus, the object of the invention is to provide a steel sheet coated with a metallic coating which does not have LME issues. It aims to make available, in particular, an easy to implement method in order to obtain a part which does not have LME issues after the forming and/or the welding.
This object is achieved by providing a steel sheet according to claim 1. The steel sheet can also comprise any characteristics of claims 2 to 12. Another object is achieved by providing a method according to claim 13. The method can also comprise any characteristics of claims 14 to 17.
Another object is achieved by providing a spot welded joint according to claim 18. The spot welded joint can also comprise characteristics of claims 19 to 22.
Finally, another object is achieved by providing the use of the steel sheet or the assembly according to claim 23.
Other characteristics and advantages of the invention will become apparent from the following detailed description of the invention.
The designation "steel" or "steel sheet" means a steel sheet, a coil, a plate having a composition allowing the part to achieve a tensile strength up to 2500 MPa and more preferably up to 2000MPa. For example, the tensile strength is above or equal to 500 MPa, preferably above or equal to 980 MPa, advantageously above or equal to 1180 MPa and even above or equal 1470 MPa.
The invention relates to a steel sheet coated with a coating comprising from 10 to 40% of nickel, the balance being zinc, such steel sheet having a microstructure comprising from 1 to 50% of residual austenite, from 1 to 60% of martensite and optionally at least one element chosen from: bainite, ferrite, cementite and pearlite, and the following chemical composition in weight:
0.10 < C < 0.50%,
1.0 < Mn < 5.0%,

Thus, by applying the method according to the present invention, it is possible to obtain zinc-nickel intermetallic compounds during above heating step. These intermetallic compounds have high melting temperature and remain solid during above heating step and thus prevents LME.

Advantageously, the steel sheet has a microstructure comprising from 10 to 40% of bainite, such bainite comprising from 10 to 20% of lower bainite, from 0 to 15% of upper bainite and from 0 to 5% of carbide free bainite.
Preferably, the steel sheet has a microstructure comprising from 1 to 25% of ferrite.

Preferably, the coating in step B) is deposited by vacuum deposition or electro-plating method. Advantageously, the coating is deposited by electro-plating method.
After the manufacture of a steel sheet, in order to produce some parts of a vehicle, it is known to assembly by welding two metal sheets. Thus, a spot welded joint is formed during the welding of at least two metal sheets, said spot being the link between the at least two metal sheets.
