The CrFeCoNi coating was fabricated by the laser remelting method. microstructure of detected. corrosion behavior at different temperatures investigated electrochemical measurements. Potentiodynamic polarization test results indicated that current density increased with increase in solution temperature 3.5 wt% NaCl and 0.5 mol/L H2SO4 solutions, suggesting exhibited higher resistance to attack ...

Precipitation-hardening (PH) stainless steels (SS) are widely used in various aerospace applications. These exhibit good mechanical and corrosion resistance. The electrochemical behavior of 15-5PH, 17-4PH, Custom450 AM 350 passivated with citric nitric acid baths for 60 90 min at 25 49 °C were evaluated 5 wt.% sodium chloride (NaCl) 1 sulfuric (H2SO4) solutions. was studied potentiodynamic pola...

The possibility of producing stable oil-in-water (O/W) emulsions containing oil droplets surrounded by multiple layer interfacial membranes from food grade ingredients has been demonstrated. These emulsions were produced using a three stage process that relies on the adsorption of charged biopolymers to oppositely charged surfaces. Emulsions (0.5 wt % corn oil, 0.1 wt % lecithin, 0.0078 wt % ch...

In order to improve the seawater corrosion resistance of Inconel 718 superalloy, a La2Zr2O7/NiCoCrAlY thermal barrier coating resistant 3.5 wt.% NaCl aqueous solution was prepared by laser cladding on superalloy. X-ray diffraction (XRD), Scanning Electron Microscope (SEM), and electrochemical techniques were used study microstructure performance in solution. The results show that is mainly comp...

WNK3 kinase is expressed throughout the nephron and acts as a positive regulator of NKCC2 and NCC in vitro. Here we addressed the in vivo relevance of WNK3 using WNK3-deficient mice. WNK3-/- mice were viable and showed no gross abnormalities. The net tubular function was similar in wild-type (WT) and WNK3-/- mice as assessed by determination of 24-h urine output (1.63 ± .06 in WT and 1.55 ± .1 ...

This study investigates the corrosion behavior of three stainless steel grades at two H2SO4 concentrations, namely 1 wt% and 10 wt%, with varying NaCl concentrations in range from 500 mg/L to 10,000 mg/L. Dissociation sulfuric acid yields hydrogen (H+) sulfate () ions, former which lowers pH value a solution while latter increases concentration ions that act as inhibitor. The equilibrium chemis...

The corrosion performances of rolled AZ31 alloy with addition Y and Gd were comparatively investigated. rates modified 3.3 3.7 mm/y immersing for 24 h in 3.5 wt% NaCl solution, respectively, which much lower than that (23.6 mm/y). remarkable improvement performance by adding or was ascribed to preferentially form less noble Al2Y Al6GdMn6 more protective product layer, resulting the reduction H2...

In this study, a mixed matrix polyethersulfone/iron-nickel oxide nanoparticle nanofiltration membrane was prepared by the solution casting technique. Polyvinylpyrrolidone was also used as a membrane pore former in membrane fabrication. The effect of iron-nickel oxide nanoparticles concentration in the casting solution on the membrane structure and performance was investigated. Scanning...
