The Electrochemical Behavior of Al Alloys in NaCl Solution in the Presence of Pyrazole Derivative
This paper studies the corrosion inhibition of Al-Mg alloy system in 0.5 mol/dm3 NaCl solution in the presence of pyrazole derivative using potentiodynamic polarization and linear polarization method. The inhibition efficiency as a function of concentration and temperature was investigated. From the polarization curves, it can be concluded that the pyrazole derivative be...
متن کاملCorrosion Behavior of Novel Mg-9Li-7Al-1Sn and Mg-9Li-5Al-3Sn-1Zn Alloys in NaCl Aqueous Solution
Corrosion behavior of two multiphase Mg-Li-Al-based alloys in 0.6 M NaCl aqueous solution is investigated by hydrogen gas evolution measurement and electrochemical test. This paper reports, for the first time, the comparison of hydrogen evolution and Tafel extrapolation results of Mg-Li-Al-based alloys. The corrosion rate of Mg-9Li-7Al-1Sn is observed to be reasonably higher when compared to th...
متن کاملOn the electrochemical dealloying of Al-based alloys in a NaCl aqueous solution.
The electrochemical dealloying of rapidly solidified Al-based alloys in a 1 M NaCl aqueous solution has been investigated using electrochemical measurements in combination with microstructural analysis. The results show that nanoporous metals (Au, Ag, Pd and Cu) with various morphologies can be fabricated through electrochemical dealloying of the Al-based alloys in the NaCl solution. The electr...
متن کاملThe Role of Mg2Si in the Corrosion Behavior of Al-Si-Mg Alloys for Pressureless Infiltration
The role of Mg2Si in the electrochemical behavior of Al-Si-Mg aluminum alloys has been studied using four experimental aluminum alloys with variations in the Si/Mg molar ratio (A1-0.12, A2-0.49, A3-0.89, A4-1.05), in neutral aerated 0.1M NaCl solutions. Accordingly, the corrosion potential in open circuit (Eoc) and polarization resistance (Rp) were measured. Results show that the augment in Si/...
