摘　　要：在热镀锌镀液中加入微量铈,对其所形成的镀层在酸性和中性介质中的耐腐蚀性进行了测定和分析。结果表明,在镀液中加入约0.05%的金属铈,能显著提高锌镀层在酸性介质中的耐腐蚀性能;在镀液中加入约0.1%的金属铈,锌镀层在中性介质中的耐腐蚀性能最好。Corrosion resistance in acidic and neutral media of the zinc alloy layer was measured and analysed. The zinc alloy layer was formed in hot - dip melt with Ce. The result showed that it can improve corrosion resistance of coat in acid medium when 0.05% Ce was added to Zn hquid. The corrosion resistance of hot - dip galvanized steel in neutral medium is best when 0.1% Ce was added to Zn liquid.
