Abstract
A pre-coated metallic substrate wherein a bare metallic substrate having a reflectance higher or equal to 60% at all wavelengths between 0.5 and 5.0 μm is coated with a pre-coating including at least one titanate and at least one nanoparticle; a method for the manufacture of this pre-coated metallic substrate; a method for the manufacture of a coated metallic substrate and a coated metallic substrate.
Claims24
A pre-coated metallic substrate comprising:
- a bare metallic substrate having a reflectance higher or equal to 60% at all wavelengths between 0.5 and 5.0 μm, the bare metallic substrate is selected from the group consisting of:
- copper, aluminum, magnesium, platinum, rhodium, tantalum, silver and gold;
- a pre-coating coating the bare metallic substrate and including at least one titanate and at least one nanoparticle selected from the group consisting of:
- TiO2, SiO2, Yttria-stabilized zirconia (YSZ), Al2O3, MoO3, CrO3, CeO2 and mixtures thereof, wherein the at least one titanate has a particle size distribution between 1 and 40 μm;
- wherein the pre-coating reduces the metallic substrate reflectance below 30% at all wavelengths between 0.5 and 5.0 μm.
