纯镁和Mg-14Li合金耐蚀性与表面膜的对比(英文)
发布时间:2021-12-21 23:29
采用析氢实验、失重实验、电化学实验、原位电化学拉曼光谱实验以及显微组织观察(光学与扫描电子显微镜)等实验方法,对比研究密排六方结构(HCP)的纯镁和体心立方结构(BCC)的二元Mg-14Li合金(质量分数,%)在0.1 mol/L NaCl溶液中的腐蚀行为与表面膜结构。实验结果表明:纯镁的耐蚀性优于Mg-14Li合金的,并且两种材料表面膜的保护功能均随着浸泡时间(16h内)的延长而提高。通过扫描电子显微形貌分析,发现不同于纯镁表面形成的较薄且呈片状的Mg(OH)2膜层,Mg-14Li合金表面形成较厚且呈交织针状含有Li2CO3的膜层;然而,两种材料的表面膜均在高的阳极过电位下发生破损。因此,两种材料的不同腐蚀抗性可归功于在其表面形成不同的保护膜。
