Le monofluorophosphate de manganese: Une nouvelle classe d'inhibiteurs de corrosion

Add time:07/22/2019    Source:sciencedirect.com

Manganese monofluorophosphate : a new classe of corrosion inhibitors. The preparation of manganese monofluorophosphate by the process of Lange was investigated. To characterize the resulting compound, analytical techniques including infra-red spectroscopy (IR), Thermogravimetric Analysis (TGA) and Differential Thermal analysis (DTA) were used. The use of manganese monofluorophosphate as a corrosion inhibitor in NaCl 3% medium during summer was investigated by electrochemical techniques such as polarization curves and open-circuit potential measurements. However, the determination of the chemical nature of the film required the use of surface analysis techniques such as scanning electron microscope (MEB) and photo electron spectroscopy (ESCA).
