Opis:: The inhibitive action of phytic acid (PA) on Q235 mild steel corrosion in 1 M HCl environment was investigated using electrochemical techniques. Polarization results revealed PA to be a mixed- type inhibitor in 1 M HCl environment, while impedance results provide evidence of adsorption of the PA species on the corroding metal surface. The adsorption of PA obeyed Langmuir adsorption isotherm. Scanning electron microscopy (SEM), atomic force microscopy (AFM) and Fourier transform infrared spectroscopy (FTIR) studies all revealed the formation of a protective film adsorbed on the steel surface.

Opis:: The changes taking place with the corrosion-resistant coating, but not the state of the surface subjected to corrosion are investigated in this paper in contrast to traditional approaches. We used the method of nitrogen relaxometry NQR and multi-exponential inversion of decay of longitudinal and transverse components of the nuclear magnetization is applied for the first time for this purpose. The results of experimental studies of changes in the distributions of spin-spin and spin-lattice relaxation of crystallite powder of sodium nitrite and urotropin, the mixture of which is used as a corrosion inhibitor of ferrous metals are considered.
