| 主权项 | 1. A steel substrate suitable for forming operations comprising: the substrate in the form of a strip, sheet or blank, the substrate being of steel or steel having a zinc or zinc-alloy coating, a corrosion protective coating directly over the substrate, wherein the corrosion protective coating comprises a first intermediate nano-layer of oxide nanoparticles, anda second top layer of polyamide-imide directly over the nano-layer, wherein the oxide-nanoparticles have a particle size between 60 and 100 nm, and the first intermediate nano-layer consists of the oxide nanoparticles and a binder selected from at least one member of the group consisting of polyols, polyacrylates, and polyamines. | ||
