Due to the unique properties of steel, including its hardness, durability, and superconductivity, which make it an essential material in many industries, lacks corrosion resistance. Herewith, two novel triazole-thione Schiff bases, namely, (E)-5-methyl-4-((thiophen-2-ylmethylene)amino)-2,4-dihydro-3H-1,2,4-triazole-3-thione (TMAT) (E)-4-(((5-(dimethylamino)thiophen-2-yl)methylene)amino)-5-methyl-2,4-dihydro-3H-1,2,4-triazole-3-thione (DMTMAT), were synthesized characterized. The inhibition...
Abstract Various methodologies are practically used to control corrosion. Coatings the most widely protect metals against However, due weak resistance of polymer coating penetration corrosive solution metal/coating interface, long-term corrosion is reduced gradually. Recently, nanoparticles have been added coatings improve their chemical, mechanical and optical properties. Nanocoatings either constituents in nanoscale or made out layers that under 100 nm. effectively lessen impact a...
A new series of heterocyclic Schiff base complexes derived from the condensation nicotinohydrazide with different aldehyde, followed by metalation Co (II) and Cu metal ions. The chemical structures synthesized compounds have been characterized elemental analysis, Fourier transform infrared spectroscopy, proton nuclear magnetic resonance, ultraviolet–visible susceptibility. spectral data confirmed their structures, furthermore, geometry were square‐planar or distorted tetrahedral. X‐ray...
Herein, the inhibition impacts of chitin, pectin, and amylopectin as carbohydrate polymers on corrosion mild steel in 0.5 M HCl were researched utilizing various experimental theoretical tools. The acquired outcomes showed that efficiencies (% IEs) tested increased by raising their concentrations these biopolymers acting mixed-kind inhibitors with major anodic ones. % IEs values reduced rising temperature. higher inferred via powerful adsorption polymeric molecules surface such obeyed...
Metal corrosion is one of the problems that pose a serious threat to many industries, due damage it causes metal parts, especially those made steel. Thence, researchers are constantly interested in finding simple and inexpensive solutions this. Using combination experimental theoretical explorations, N-(Butylidene)-5-(3,3-Dimethyltriaz-1-en-1-yl)-1H-Imidazole-4-Carboxamide (BDIC) was investigated as an inhibitor carbon steel 1 M HCl solution. The inhibitory effectiveness increased with...
Modified uncrosslinked and crosslinked chitosan derivatives were investigated as green sorbents for the removal of copper (Cu2+) lead (Pb2+) cations from simulated solutions. In this regard, N, O carboxymethyl (N, CMC), beads (Cs-g-GA), with glutaraldehyde/methylene bisacrylamide (Cs/GA/MBA), GA/epichlorohydrin (Cs/GA/ECH) prepared characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy analyses. Atomic force...
During the mandatory acidification process in oil and gas industry, carbon steel unfortunately suffers significant corrosion damage. From this perspective, for first time a new ionic liquid called 1-(2-(4-bromophenyl)-2-oxoethyl)-4-(tert-butyl)pyridin-1-ium bromide (ILB) has been used as an effective inhibitor aggressive HCl solution (15%) at 298 K. The experiments were managed with number of different chemical electrochemical techniques including weight loss, potentiodynamic polarization...
This paper investigates the performances of two synthesized formamidine derivatives, namely: N,N-dimethyl-N'-(pyridin-2-yl) (A) and N,N-dimethyl-N'-(pyrimidin-2-yl) (B) to inhibit corrosion copper in 1.0 M HNO3 solution at fixed temperatures. Different tools, viz. electrochemical, chemical, microscopic techniques were utilized this paper. The evaluated inhibition efficiencies (% IEs) tested derivatives increased with their concentrations. Results indicated that compounds acted as mixed-kind...
In this report, N-benzylhydrazinecarbothioamide (BHCTA) was investigated as an organic inhibitor for the corrosion of copper substrate in 3.5 wt.% sodium chloride electrolyte at 298 K. The inhibition efficiency BHCTA examined using electrochemical, chemical and theoretical tools. gained outcomes indicated a supreme which exceeded 95 % upon addition 1.00 mM BHCTA.
