The protective action of two vapour phase inhibitors on the corrosion of mild steel

The action of two vapour phase inhibitors (VPI), dicyclohexyl-ammonium nitrite (DICHAN) and dicyclohexylamine (DICHAMIN), on the atmospheric corrosion of mild steel at a relative humidity of 100% and under isothermal conditions (25 °C) has been studied. In order to obtain electrochemical data with thin adsorbed moisture layers a vapour phase inhibitor monitor (VPIM) was developed. A check of the data was done by three electrochemical techniques and by the image analysis technique. The tests carried out have revealed that the corrosion rate of mild steel decreases in the presence of DICHAN and DICHAMIN. With the VPIM and the electrochemical techniques used it is possible to understand the inhibition mechanism of these two vapour inhibitors on the atmospheric corrosion of steel.     

Characterization of the Interactions of vapour phase inhibitors on metal surfaces by ellipsometry

The interaction of dicyclohexyl ammonium nitrite (DICHAN) and dicyclohexylamine (DICHAMIN) on substrates of pure iron and platinum were investigated by ellipsometry. The initial immersion phase (≤ 100 min) under isothermal conditions (20°C) in air of relative humidity (RH) = 0 or (RH) = 100% was investigated. It is shown, that DICHAN is intensively adsorbed on the primary oxide layer of iron materials and causes effective hydrophobing. DICHAMIN to a lower extent decreases the adsorbability of water and when influenced by air of (RH) = 0%, it is completely desorbed. On the basis of the results presented, the actual views on the active principles of vapour phase inhibitors of the iron materials' atmospheric corrosion are defined.     

Examination of the influence of vapour phase inhibitors on the wettability of the iron surface by contact angle measurements

The influence of dicyclohexyl ammonium nitrite (DICHAN) and dicyclohexylamine (DICHAMIN) on the interfacial-energetic behaviour of the real iron surface was estimated by means of approximation equations by the evaluation of contact angle measurements (advancing angle) on system of primary-oxidecovered iron/liquid/gas. The presented results support the statement having be made already from ellipsometric investigations that the hydrophobicity of the iron surface during the initial phase of the contact with DICHAN is caused by its adsorption, whereas in the case of DICHAMIN it is brought about probably by protolytic interactions with the surface hydroxyl groups of the primary oxide layer of iron and contributes to the stabilization of the passive state, too.
