Abstract
A pre-coated steel substrate coated with: —optionally, an anticorrosion coating and—a flux including at least one titanate and at least one nanoparticle chosen from: TiO2, SiO2, Yttria-stabilized zirconia (YSZ), Al2O3, MoO3, CrO3, CeO2 or a mixture thereof, the thickness of the flux being between 30 and 95 μm.
Claims21
A pre-coated steel substrate comprising:
- a steel substrate;
- and
- a flux coating the steel substrate and including at least one titanate, wherein a diameter of the at least one titanate is between 1 and 40 μm, and at least one nanoparticle selected from the group consisting of:
- TiO2, SiO2, Yttria-stabilized zirconia (YSZ), Al2O3, MoO3, CrO3, CeO2 and mixtures thereof, a thickness of the flux being between 30 and 95 μm.

A method for the manufacture of an assembly comprising the following successive steps:
- providing at least two metallic substrates wherein a first of the at least two metallic substrates is a pre-coated steel substrate coated with a flux including at least one titanate, wherein a diameter of the at least one titanate is between 1 and 40 μm, and at least one nanoparticle selected from the group consisting of:
- TiO2, SiO2, Yttria-stabilized zirconia (YSZ), Al2O3, MoO3, CrO3, CeO2 and mixtures thereof, a thickness of the flux being between 30 and 95 μm;
- and
- welding the at least two metallic substrates by TIG welding.
