Korrosionsbeständige Reinzink- oder Teilzinkplattierte Stahlbleche sowie Verfahren zu ihrer Herstellung.

摘要

A Zn or part-Zn plated steel sheet has an MgO coating thereon which increases corrosion resistance and plating adherence. The MgO coating is formed by coating according to the sol-gel method or by dipping or treating by cathodic electrolysis a Zn or part-Zn plated steel sheet in a molten salt bath mainly containing a magnesium salt.
