摘要: 利用阳极极化曲线和交流阻抗技术研究了新型板栅合金与传统合金的耐腐蚀性能。应用现代表面技术XPS和XRD研究了合金在0.9V下腐蚀6h所形成的阳极腐蚀膜的组成。结果表明，新型铅钙合金的耐腐蚀性能优于传统合金，其阳极腐蚀膜中导电性差的二价铅含量减少，四氧化铅的含量增大，其阳极腐蚀膜的电阻减少；新型铅钙合金可以明显改善铅酸电池的深循环性能，可以作为新一代免维护铅酸电池的板栅材料。

Abstract：The corrosion-resistance properties of new grid alloy and traditional alloy were studied using anodic polarization curve and A.C impendance. The anodic films of comparative alloys formed in sulfuric solution at anodic 0.9V potential corrosion for 6h were investigated by means of XPS and XRD methods. The result showed that new grid alloy has batter corrosion-resistance behavior than that of traditional alloy, the growth of Pb(Ⅱ) dioxide in new alloy surface layer was inhabited. By means of A.C impendance method, the resistor of the corrosion layers were decreased, it was found that the new alloy can encourage the development of PbO2 in the scale, and enhance the conductivity of the anocdic scale, then, the deep recycling properties of the battery was promoted greatly. The new alloy can serve as the candidate for the grid material in maintenance-free lead/acid battery.

Key words： new alloy anodic films XPS A.C impendance
