Abstract: A flat steel product for hot forming may be produced from a steel substrate that includes a steel comprising 0.1-3% by weight Mn and up to 0.01% by weight B, along with a protective coating that is applied to the steel substrate. The protective coating may be based on Al and may contain up to 20% by weight of other alloy elements. Also disclosed are methods for producing such flat steel products, steel components, and methods for producing steel components. Absorption of hydrogen is minimized during heating necessary for hot forming. This is achieved at least in part through an alloy constituent of 0.1-0.5% by weight of at least one alkaline earth or transition metal in the protective coating, wherein an oxide of the alkaline earth or transition metal is formed on an outer surface of the protective coating during hot forming of the flat steel product.

Abstract: Yttria stabilized zirconia (YSZ) particles (40) form a thermal barrier layer (58) on a metal substrate (24). The YSZ particles have a porous interior (52, 54) and a fully melted and solidified outer shell (50). The thermal barrier layer may have porosity greater than 12%, including porosity within the particles and inter-particle gap porosity. Inter-particle gaps may be greater than 5 microns. The thermal barrier layer may exhibit elastic hysteresis and an average modulus of elasticity of 15-25 GPa. A bond coat (44A, 44B) may be applied between the substrate and the thermal barrier layer. The bond coat may have a first dense MCrAlY layer (44A) on the substrate and a second rough, porous MCrAlY layer (44B) on the first MCrAlY layer, the bond layers diffusion bonded to each other and to the substrate.
