摘要
通过调整铅合金中钙与锡的含量,测试各个合金样品的腐蚀速率、时效硬化情况、金相结构和电化学性能,发现锡与钙的比值为30时(3#样品),腐蚀速率最小。钙含量高的样品时效硬化时间短,但不利于合金的耐腐蚀性,发现钙含量低的样品容易氧化成硫酸铅,锡的存在能够抑制该过程的进行,通过研究能够改善高温储能电池板栅合金的耐腐蚀性能。
By adjusting the content of Ca and Sn in lead-alloy, the corrosion rate, aging hardening, metallographic structure and electrochemical test properties of each alloy sample are tested, when the ratio of Sn to Ca was 30(3#samples), the corrosion rate was the lowest. Age hardening is short when Ca content of the sample is high, but it doesn't favor the corrosion resistance of alloy. Finally it is found that the sample of the low Ca content easily oxidized to lead sulfate, the existence of the Sn can inhibit the process. The research can improve the corrosion resistance of high temperature energy storage panel grid alloy.
