Ternäre Zinn-Zink-Legierungen, galvanische Bäder und galvanisches Verfahren zur Erzeugung von ternären Zinn-Zink-Legierungsschichten

摘要

The invention relates to ternary tin zinc alloy coatings 30 - 65 wt. % tin, 30 - 65 wt. % zinc and 0.1 - 15 wt . % metal from the following group as a third alloy component; iron, cobalt, nickel. Correspondingly, alloy coatings can be produced by means of electrolytic deposition from aqueous galvanic electroplating solutions which contain the components of the alloy in a dissolved form. The alloy coatings are characterised in that they have a particularly high resistance to corrosion and are particularly suitable as anti-corrosion protective coatings on iron-based materials.
