Özet
A study was conducted to assess the inhibitive effect of Diospyros kaki leaves extract on St37 steel corrosion in 0.1 M HCl solution. Electrochemical (PDP, EIS, DEIS), chemical, and surface morphological screening (SEM, EDS, FTIR) techniques were used in the study. Results show that D. kaki leaves extract is an excellent inhibitor for St37 steel in HCl solution. Maximum inhibition efficiency of 91% was afforded by the highest studied concentration of the extract from PDP measurements. PDP results reveal that the extract components act principally as cathodic type inhibitor suppressing the reduction of hydrogen ions in the cathodic region of the metal. DEIS results show that the studied systems exhibit non-stationary character and the adsorbed extract components were stable particularly at long exposure time. SEM, EDAX, and FTIR results support experimental results that components of D. kaki leaves extract were adsorbed on St37 surface.
