摘要：
This work aims to study the impact of zinc cation and 2-mercaptobenzoxzole (MBO) on the corrosion protection of a silane sol-gel coating on mild steel. First, effectiveness of the organic and inorganic inhibitors on the corrosion of bare mild steel in a NaCl solution was shown to be linked to formation of a surface film. Using electrochemical data as well as results of surface analysis, a sharp inhibition synergism was found when an equal mole percentage of ZnCl2 and MBO was added to the NaC1 solution. Finally, electrochemical data indicated superior performance of the coating with the combination of inhibitors. (C) 2016 The Korean Society of Industrial and Engineering Chemistry.
