The initial corrosion behavior of AZ63 magnesium alloy was investigated in 1, 3, 5 and 7 wt.% NaCl solutions by means potential, linear polarization, electrochemical impedance spectroscopy, polarization measurements, during exposure the media. Results show that increase chloride concentration provokes an rate. Based on obtained kinetics parameters mechanisms anodic dissolution hydrogen evolutio...

In this study, an  organic compound  inhibitor, namely N-benzyl-N-(4-chlorophenyl)-1H-tetrazole-5-amine (NBTA), was synthesized and the role of this inhibitor for corrosion protection of stainless steel (SS) exposed to 0.5 M H2SO4 was investigated using electrochemical, and quantum analysis. By taking advantage of potentiodynamic polarization, the inhibitory action of NBTA was found t...

Abstract: Mg2Ni alloy and Mg2Ni–x wt% TiO2 (x = 3, 5 and 10 wt %) composites are prepared by mechanical alloying. The produced alloy and composites are characterized as the particles with nanocrystalline/amorphous structure. The effects of TiO2 on hydrogen storage properties are investigated using anodic polarization and electrochemical impedance spectroscopy. It is demonstrated that the initia...

The study highlights the corrosion behavior of untreated and treated tantalum with addition trimanganese tetraoxide (Mn3O4) nanoparticles in simulated inflammatory media. anodic layer was produced on pure by anodization electrolytes composed ammonium fluoride, ethylene glycol, water. Nanoparticles were deposited uniformly surface anodized electrophoretic deposition (EPD) method. results reveale...

The atmospheric corrosion of weathering steels varies as a function geographic zone, season, and other environmental variables related to that region which the experiments have been done. Meanwhile, rusting is continuous process, it main product corrosion. current study investigates effects rust on steel in localized Digha, sea resort West Bengal, India. investigations performed by purposely ac...

This paper presents the results of study that was undertaken to investigate the ability of a new antiscale, polyacrylamide in solving problems found in cooling water systems. The effects of the polymer on C-steel and copper dissolution in synthetic cooling water environment were studied through scale, Tafel, and Linear polarization measurements. The results obtained from this study showed that ...

The aqueous corrosion resistances of galvalume (FeAl+Zn) and steel galvanized (Fe-Zn) alloys, passivated by immersion in chromating solution with different immersion times (0, 10, 30 y 60 s) are compared. The electrochemical behaviour of various chromated and non-chromated coatings was investigated in 3 wt-% NaCl solution using polarization techniques. For comparison, AISI 1010 carbon steel sub...

Blown-powder laser surface alloying was performed on the magnesium alloy AZ91D with Al-Si alloy powder to improve corrosion resistance. Characterization by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and x-ray diffraction (XRD) analysis revealed that intermetallic compounds (IMCs) of Mg2Si, Al12Mg17 and Al3Mg2 were formed in the matrix of α-Mg and Al solid solutions...
