5-Arylpyrimido-[4,5-b]quinoline-diones as new and sustainable corrosion inhibitors for mild steel in 1 M HCl: a combined experimental and theoretical approach

The inhibition of mild steel corrosion in 1 M HCl by four 5-arylpyrimido-[4,5-<italic>b</italic>]-quinoline-diones has been investigated using weight loss, electrochemical, surface, and quantum chemical calculations and molecular dynamics simulation methods.
