【Abstract】 The working mechanism of corrosion inhibitors is in close relationship with the formation of inhibitor self- assembled monolayers (SAMs) on metal surfaces. An outstanding advantage of scanning tunneling microscopy (STM) is to provide a direct image of the atomic structure, which has made it an irreplaceable tool in the research field of metal corrosion science. In this paper, the progress in investigating the structure, properties and crystal- plane structural effect of inhibitor SAMs formed on some engineering metal surfaces using STM in recent years is reviewed.更多还原
