ZAM (Zn\u2013Al\u2013Mg) steel<\/span><\/strong> is becoming a noteworthy material solution in applications requiring high corrosion resistance. However, the effectiveness of the coating depends not only on the Zn\u2013Al\u2013Mg composition but also significantly on the <\/span>chemical system used for surface treatment before and after plating<\/span><\/strong> .<\/span><\/p>\n<\/div>\n

In particular, <\/span>post-plating processing \u2013 especially passivation and thin organic coating (TOC)<\/span><\/strong> \u2013 is increasingly emphasized to control surface corrosion, maintain appearance, minimize fingerprints, and support machining processes. Research on Zn\u2013Al\u2013Mg surface treatment systems also shows that both Cr3+ passivation and non-chromium passivation can significantly improve protection compared to using only anti-corrosion oil.<\/span><\/p>\n
