In this paper, electrochemical behavior of epoxy paints embedded by modified calcium carbonate particles was investigated during exposure to 3.5 wt% NaCl solution. The precipitated calcium carbonate (PCC) and ground calcium carbonate (GCC) particles were utilized as inexpensive filler for epoxy paints. Electrochemical impedance spectroscopy (EIS), polarization tests and pin-on-disk method w...

Four distinct types of fluid inclusion are associated with brecciation, alteration and mineralization in the Ilkwang Cu–W breccia-pipe deposit in the southeastern Kyongsang Basin, South Korea. The earliest fluid inclusions in igneous quartz have salinities of 35–49 wt% NaCl equiv. and homogenize by halite dissolution. This fluid exsolved directly from the melt. A CO2-bearing fluid (2–4 wt% NaCl...

Ball-milled hydroreactive powders of Mg-Al scrap with 20 wt.% additive (Wood’s alloy, KCl, and their mixture) no additives were manufactured. Their hydrogen yields reaction rates in a 3.5 NaCl aqueous solution at 15–35 °C compared. In the beginning reaction, samples KCl (20 wt.%) Wood’s alloy (10 provided highest second-highest rates, respectively. However, after 4 h correspondingly lowest seco...

The inhibition mechanism of sodium oleate (C17H33COONa) for pitting corrosion of aluminum alloy (AA) 2024 in 0.1 mol L NaCl solution was investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), scanning electron microscopy with energy dispersive spectrometer (SEM-EDS) and X-ray photoelectron spectroscopy (XPS). C17H33COONa showed good inhibition effect on u...
