Experimental and theoretical insights into the corrosion inhibition activity of novel Schiff bases for aluminum alloy in acidic medium

Abstract

Novel Schiff bases characterized through spectroscopic techniques and used as anticorrosive agents for aluminium alloy acidic medium. Electrochemical techniques and DFT studies were used to study inhibition effect and molecular interactions.

Corrosion protection of aluminum alloy (AA2219-T6) using sulfonic acid-doped conducting polymer coatings

“…Extensive research on the microstructural and mechanical properties of aluminum alloy AA2219 has revealed its potential applications in the aerospace and marine industry. [1][2][3][4] Owing to its lightweight, low density and high mechanical strength, it is a widely applied alloy in the marine industry. 1,[5][6][7] Generally, it is prone to mild pitting corrosion induced by aggressive chloride ions in seawater and the harsh marine environment.…”

Corrosion inhibition studies of ferrocenyl Schiff bases in a mild acidic medium through experimental methods and DFT calculations

“…In our last work, we synthesized organic anlogoues of Schiff bases and ferrocenyl Schiff bases and investigated them as efficient corrosion inhibitors for aluminium alloy AA2219-T6. 52,53 Following the same research line here in this piece of work, we aimed at the synthesis of ferrocenyl Schiff bases by varying the alkyl chain length in their structure and their corrosion inhibition efficiency in an acidic medium. The main advantage of the synthesis of these molecules lies in the fact that they were easily prepared and showed very good inhibition efficiency towards alloy substrate.…”

Environmentally-friendly Inhibitor From Waste for Aluminium Corrosion in 0.5M Sulphuric Acid Environment

“…Still, an inhibitor is regarded as one of the most cost-effective and convenient means of ghting corrosion, particularly in acid solutions [7][8][9][10][11][12]. The corrosion inhibitive behavior of aluminium in an acid medium using different organic compounds with polar functions such as sulphur, phosphorous, oxygen, and nitrogen has been documented [13][14][15][16][17][18][19][20][21][22][23]. Several processes in the industry have used inorganic and organic inhibitors for corrosion defense, but due to their toxicity and high cost, research awareness has moved towards the use of e cient, cost-effective, nontoxic, and benign corrosion inhibitors.…”
