The electrochemical corrosion inhi- bition of the combined admixture of vanillin and 1, 4-diaminobenzene (VDB), and vanillin with sodium molybdenum oxide (VSMO) on carbon steel in 1 M H 2 SO 4 and HCl solutions was evaluated with weight loss measurement. Results show VDB performed more effec- tively in both acids with average inhibition efficiency above 85% in HCl and 90% in H 2 SO 4 compared to VSMO whose average inhibition efficiency is slightly above 70% in HClapplication/pdfT Technology (General), TJ Mechanical engineering and machineryArticle
