【摘要】 对生物医用的T42NG经3Cr13不锈钢复合构成的T42NG钛合金"双金属材料",在常温常常压下3 5%的NaCl水溶液中,采用"三电极体系"实验装置运用恒电位法测定其阳极稳态极化曲线,对其电化学腐蚀行为进行了系统地研究。结果表明:经3Cr13不锈钢复合后的T42NG钛合金,其电极过程的阳极稳态极化曲线几乎只有纯化区和析氧区,不易发生腐蚀。更多还原

【Abstract】 Using a lab constant potential method to determine anodic stead polarization curves,the authors systematically studied electrochemical corrosion reaction of titanium alloys applied to biomedicine,such as T42NG titanium alloys bimetals,which were compounded by 3Cr13 stainless steels,at normal room temperature and air pressure,in the 3.5% NaCl water solution.The results obtained showed that in the process of electrode,the anodic steady polarization of T742 NG titanium alloys bimetals compounded by curves almost had only passivation regions and oxygen evolution regions and stable passivation potential regions,and this kind of compounded titanium alloys bimetals could not be destroyed easity.更多还原
