COATED METAL SUBSTRATE AND METHOD OF MAKING Russian patent published in 2020 - IPC C23C28/00 C23C16/06 C23C16/44 C23C14/16 C23C14/24 

FIELD: technological processes.

SUBSTANCE: disclosed group of inventions relates to a coated metal substrate, a method for production thereof and use of said coated metal substrate for making an automotive vehicle. Coated metal substrate contains at least one oxide layer directly coated with an intermediate layer containing Fe, Ni, Cr and Ti, wherein amount of Ti is higher than or equal to 5 wt%, wherein the following ratio of 8 wt% < Cr + Ti < 40 wt%, Fe and Ni – the rest. Anti-corrosive metal coating layer is arranged directly above said intermediate layer. Method of producing coated metal substrate is as follows. Providing presence of metal substrate, having at least one layer of oxides. Said intermediate layer with thickness of 1–100 nm is applied by vacuum sputtering or electrodeposition. An anticorrosive metal layer containing a component selected from a group containing zinc, aluminum, copper, silicon, iron, magnesium, titanium, nickel, chromium, manganese and their alloys is applied.

EFFECT: coating is provided with improved adhesion of layers on the substrate, which does not require removal of oxides present on the surface of the substrate.
