摘要/Abstract

摘要：

目的　研究Vitallium 2000+钴铬钼合金对日常奶类饮品的耐腐蚀性。方法　使用电化学工作站及电化学分析仪测绘Vitallium合金在几种日常奶类饮品中的动电位极化曲线，测得自腐蚀电位(Ecorr)、自腐蚀电流密度(Icorr)和极化电阻(Rp),以人工唾液为对照组进行比较分析。应用场发射扫描电子显微镜(FSEM)观察试样，比较腐蚀前及腐蚀后实验组与对照组之间形貌差异。结果　Vitallium合金在三种实验组溶液中,Icorr增大,Ecorr和极化电阻(Rp)降低,耐腐蚀性能与对照组人工唾液有显著性差异(P<0.05)。结论　纯牛奶、豆奶、酸奶可使Vitallium合金的耐腐蚀性能明显下降。

Abstract: Abstract: Objective To study the corrosion resistance of Vitallium 2000 plus Co-Cr-Mo alloy in different milk beverages. Methods Compared with artificial saliva (the control group), electro chemical technique was used to measure the electric potential of corrosion (Ecorr), current density of corrosion (Icorr) and polarization resistance (Rp) of Vitallium 2000 plus Co-Cr-Mo alloy in different dairy products. After electrochemical analysis, microstructural and phase diffraction was examined by FSEM to compare the morphological differences between groups before and after the corrosion. Results The Icorr of Vitallium 2000 plus Co-Cr-Mo alloy in three different experimental groups increased, while Ecorr and Rp decreased evidently. Compared with the control group, the corrosion resistance showed a significant difference (p<0.05). Conclusion The corrosion resistance of Vitallium 2000 plus Co-Cr-Mo alloy decrease evidently in milk, soymilk and yogurt.
