Inhibitory effect of thiamine salts on steel corrosion in an acidic environment: an experimental and theoretical approach

Key Points

• This study aims to evaluate the effectiveness of thiamine salts as corrosion inhibitors for steel in acidic environments.
• Experimental assessment of thiamine hydrochloride and thiamine pyrophosphate on steel corrosion.
• Comparison of the adsorption properties of both compounds on steel surfaces.
• Thiamine hydrochloride demonstrates stronger adsorption on steel compared to thiamine pyrophosphate, leading to greater corrosion inhibition.
