| Abstract | ||
| The inhibition of zinc of hybrid Ti/Ce salt with 0, 100, 300, 600, 900, 1200, and 1600 ppm concentrations was investigated by weight-loss (WL) estimation and potentiodynamic polarization (PDP) in 1M HCl solution. The inhibition efficiency of hybrid Ti/Ce salt was evaluated as a corrosion inhibitor by immersing the Zn in it over a period extending up to 120 h and the temperature effect (25-55 ⁰C) on inhibition of Zn. WL and the corrosion rate (C_R) were recorded after a short immersing time and 120 h of immersion. A passive layer was formed after 24 h at a high concentration of 1600 ppm hybrid Ti/Ce salt and was stable till 120 h. The surface morphology and composition of the different investigated conditions were studied by SEM and EDX analysis, respectively. | ||
