Abstract (en)
[origin: CA3172957A1] The invention relates to a method of conditioning the surface of a steel strip coated with an electrolytically deposited zinc alloy anticorrosion layer, which is subjected to an increase in temperature to alter the steel microstructure, characterized in that tin is deposited or is codeposited with zinc during the electrolytic coating of the steel strip, such that tin is present at the surface or close to the surface, or tin is applied in metallic form or ionic form after the electrolytic coating.
