中文摘要 | 黃銅廣泛被運用於腐蝕的環境,但由於黃銅中常含有鉛,易溶出,造成環境、人體上的傷害,在環保意識的抬頭下,本研究以矽取代鉛,主要目的在於探討不同微量的矽添加於無鉛黃銅對顯微組織變化及其脫鋅腐蝕性能的影響。實驗結果發現:隨著矽含量(0 wt%~1 wt%)增加,顯微結構由α、β相變為β、γ相。整體而言,抗脫鋅能力則隨著矽添加量增加而增加,經XRD、EDS測試,發現矽在黃銅中以固溶方式存在,主要固溶於β相中,因此達到矽黃銅抗脫鋅腐蝕能力提升之效果。 |
英文摘要 | Brass which contains lead is widely used in corrosive environments. Lead dissolves out brass will do harm to not only human beings but whole earth. Under the trend of green movement, this research use silicon to replace lead. The main purpose is to explore the change of the microstructure and the dezincification phenomenon by adding a trace of silicon. The experimental results show that with the silicon content (0 wt% - 1 wt%) increasing, the microstructure change from α, β phase to β, γ phase. Overall, its dezincification resistant ability improved. By XRD and EDS test, found that silicon precipitates mainly in β phase in solid solution. Thus, the dezincification resistant ability of silicon brass become better. |
