SUBSTRATE WITH COATING FOR PACKAGING APPLICATIONS AND PRODUCTION METHOD OF MENTIONED SUBSTRATE Russian patent published in 2017 - IPC C25D5/48 

FIELD: metallurgy.

SUBSTANCE: steel substrate for the cans production has the coating from one or both sides in the form of the iron-tin alloy layer, which contains at least 85 wt % FeSn (50 at % I\iron and 50 at % tin), and wherein the iron-tin alloy layer or layers are provided with the coating layer with chromium metal - chromium oxide, obtained as the result of the trivalent chromium process, the thickness of which corresponds to at least 20 mg Cr/m². The invention also relates to the mentioned coated substrate process production.

EFFECT: development of the tinplate alternative, which is not based on the hexavalent chromium use, requires the moderate amounts of tin and combines the excellent corrosion resistance with optimal optical properties.
