| 摘 要： | 在偏光显微镜下观察铅碲二元合金（Pb—Te）的组织结构。高温恒电流腐蚀后，利用扫描电镜分析Pb—Te合金的腐蚀形貌。把各合金制成电极，用循环伏安（CV）、开路电位（OCP）等方法研究了纯铅和Pb—Te合金作为正极的电化学性能。结构实验表明，掺入适量的碲可以细化铅合金的晶粒。通过观察Pb—Te合金的腐蚀形貌，发现适量的碲可以提高板栅合金的耐腐蚀性能；电化学实验表明掺碲还会抑制二氧化铅的生长，从而减轻了合金的腐蚀。

| Abstract: | The microstructure of Pb-Te binary alloys was observed using a polarizing microscope.The morphology of the corrosion sections of Pb and Pb-Te alloys were analyzed by scanning electron micro-scope(SEM) following the corrosion test.The electrochemical properties of Pb-Te alloys in sulfuric acid solution were investigated by cyclic voltammetry(CV),open circuit potential(OCP).The results indi-cate that the introduction of tellurium results in grain refinement,increased corrosion resistance for posi-tive grid al... |
