| Popis: | Mg alloys are promising materials for a variety of applications such as automobile, aerospace biomedical and energy storage, etc. Mg-1Sn alloys can be used as the anode for battery application. The corrosion characteristics of Mg-1Sn (wt. %) alloy are analyzed by electrochemical tests like Galvanostatic Electrochemical impedance spectroscopy (EIS), and Tafel slope. Mg-x Sn (1 wt. %) alloys as an anode is newly fabricated using stir and squeeze cast technique for the research. This study analyzed and compared the corrosion behavior of Mg-1Sn (wt. %) alloys in 3.5 wt. % NaCl solution with different immersion periods. An immersion test of Mg-Sn alloy was performed to access the corrosion rate by immersing the samples in NaCl Solution for the short duration of 60 minutes [ST] and 24 hours. Mg-1Sn (wt. %) alloy immersed for 24 hours in NaCl solution showed the better electrochemical performance compared to the sample immersed for 60 minutes (Rp[24 h] > Rp[ST], Icorr[24 h] < Icorr[ST], CR[24h] < CR[ST]). The improvement in the corrosion properties of Mg1Sn alloy under 24h of immersion is attributed to the formation of a protective oxide layer, thereby suppressing the transfer of chloride ions from the electrolyte solution. |
