In this work, different cationic surfactants with various aliphatic and aromatic ammonium cations were used to prepare inhibitor coatings characterized by techniques such as IR spectroscopy NMR. The prepared electrografting on the steel surface their anticorrosion properties evaluated in media (HCl, H2SO4 NaCl solutions). electrochemical potentiodynamic polarization technique was study inhibiti...

By using the developed finite-element models, we perform numerical investigation of nonstationary temperature fields and kinetics microstructural phase transformations in base material WWER -1000 reactor vessel (15Kh2NMFА steel) under conditions submerged-arc cladding protective anticorrosion layers austenitic materials. We comparative analysis results simulation obtained by two methods predict...

Efforts to widen the scope of ionic liquids applications across diverse research areas have flourished in last two decades with developments understanding and tailoring their physical, chemical, biological properties. The promising liquids-based materials as antimicrobial systems is due ability flexibility be tailored varying sizes, morphologies, surface charges. Ionic are also considered green...

Hot corrosions of laser-cladded inconel 625 in molten salt Na2SO4-MgSO4 mixture have been studied at 900 °C to address its anticorrosion behaviors. Elemental and microstructural characterizations provide direct evidence for the formation MgO/Cr2O3 external layers outward-diffusion Cr atoms. The Cr-depletion promotes precipitation δ-Ni3(Nb/Mo), nucleation accumulation dislocations, pores, intern...
