High efficiency corrosion inhibitor 8-hydroxyquinoline and its synergistic effect with sodium dodecylbenzenesulphonate on AZ91D magnesium alloy

Synergistic corrosion inhibition effect of quinoline quaternary ammonium salt and Gemini surfactant in H2S and CO2 saturated brine solution

“…Many organic compounds with oxygen, nitrogen, sulfur heteroatoms and aromatic rings, through which these organic molecules can be adsorbed on the metal surface, are considered to be effective corrosion inhibitors [2][3][4][5][6]. Their inhibition efficiency can be influenced by varieties of factors, such as metallic sort [7][8][9][10], temperature of the system [11,12], testing media [13][14][15][16] and the structure of inhibitor molecule [17].…”

Electrochemical and DFT studies of quinoline derivatives on corrosion inhibition of AA5052 aluminium alloy in NaCl solution

“…Corrosion inhibitors are often used as a cost-effective way to protect aluminium alloy. Quinoline derivatives have been used for corrosion protection of copper [8][9], steel [10][11], aluminium alloy [12] and magnesium [13]. Density functional theory (DFT) has been extensively used to study the corrosion protection mechanism of inhibitors on molecular levels [14][15][16].…”

Evaluation of the protective ability of typical corrosion inhibitors for magnesium alloys towards the Mg ZK30 variant

“…A comparative investigation of six chemical compounds with potential for inhibiting the corrosion for ZK30 magnesium alloy in chloride solution has been performed. These six chemical compounds are: ammonium phosphate dibasic [(NH 4 ) 2 HPO 4 ], 8-hydroxyquinoline (8-HQ), calcium fluoride (CaF 2 ), sodium fluoride (NaF), sodium dodecylbenzosulfonate (SDBS), zinc nitrate [Zn(NO 3 ) 2 ]; these were selected due to their potential ability, according to the literature, to inhibit corrosion of magnesium alloys [26][27][28][29]. Despite the fact that these six chemical compounds have been investigated as corrosion inhibitors in magnesium alloys, there are yet no studies available in the literature that address the influence of the aforementioned inhibitors to corrosion protection of Mg ZK30 alloy which is of particular interest as it has been studied as the best alternative of aluminium alloys in aerospace and automotive industry [5].…”
