| 摘 要： | 为了探索析出的富锰相对高锰ZA35合金电化学腐蚀性能的影响规律,根据高锰ZA35合金中富锰相的元素组成,熔炼出析出相MnAl6.采用动电位极化方法测试了富锰相MnAl6和ZA35-1.2Mn合金在NaCl水溶液中的开路电位和极化曲线,利用X-射线衍射仪(XRD)检测了合金的相组成.结果表明,随着NaCl溶液温度升高,合金的开路电位下降,并且富锰相MnAl6较ZA35-1.2Mn合金的开路电位低,富锰相MnAl6较ZA35-1.2Mn合金腐蚀电流密度大.ZA35-1.2Mn合金在NaCl含量为3.5%的溶液中,析出的富锰相MnAl6将作为阳极区优先溶解. |

| Abstract: | Precipitate phase MnAl6 was fabricated based on element distribution of Mn-enriched in high Mn ZA35 alloy to understand effects of precipitated phase on electrochemical behavior of high Mn ZA35 alloy. Open circuit potential against time and polarization curves of Mn-enriched phase MnAl6 and ZA35-1.2Mn in NaCl aqueous solution were measured by potential dynamic polarization, and phase constituent of the alloy was examined by XRD (X-ray diffraction). The results show that with increasing in temperature of NaC... |
