| Abstract: | The open-circuit potential and polarization curve of ZA35 and ZA35-0.15Sr alloys in NaOH aqueous solution at 20 ℃,40 ℃and 60 ℃ were studied by means of electrochemical workstation for studying the effect of alloying element Sr on corrosion resistance of ZA35 alloy.The result shows that: when the temperature is elevated,the open-circuit potential of alloys are gradually shifted in the negative direction,the open-circuit potential of ZA35-0.15Sr alloy is higher than that of ZA35 alloy at the same temperature;Both of the alloys dissolve during weak polarization and passive during strong polarization,the corrosion resistance of ZA35-0.15Sr alloy is higher than that of ZA35 alloy at the same temperature;Compared to ZA35 alloy,ZA35-0.15Sr alloy with refined grain and dendrite improve the corrosion resistance in NaOH solution. |
