The effect of NaClO solution on pitting behavior 304 stainless steel was investigated by electrochemical tests and composition analysis. results show that the open circuit potential (OCP) shifts to positive direction with increase [ClO−], indicating passivation film formed sample surface is faster, but, has no (Eb) in first stage (< 24 h). After h immersion, occurs because Cl− detected wake decomposition ClO− for its thermodynamics instability. In later stage, [Cl−] increases correspondingly...
The susceptibility of 17Cr ferrite stainless steel to intergranular corrosion (IGC) was investigated using the double loop electrochemical potentiokinetic reactivation (DL-EPR) test and microstructural characterisation. results show that optimised DL-EPR condition for is l M H2SO4 + 0.006 KSCN solution with a scan rate 0.1 V min−1 at 25°C severe IGC occurs in temperature range 500–650°C nose locates approximately 600°C. Ir/Ia value rises up 16.99% when heat treated 600°C 30 min. After aging...
Abstract In this study, we reviewed our recent work on the general corrosion of carbon steel (P355QL2) overpack material for isolation high‐level nuclear waste in Belgium's supercontainer concept. By using electrochemical impedance spectroscopy and by optimizing mixed potential model, which incorporates quantum mechanical tunneling charge carriers across barrier layer to describe kinetics partial cathodic process, evaluated all parameters model as a function independent variables such...
Abstract The effect of chloride threshold (CT = [Cl − ]/[SO 4 2− ]) on the pitting behaviors 316LN in sour water was studied by using electrochemical tests. result shows that resistance decreases with increase CT and temperature. critical (CCT) from 3 at 40°C to 1.5 70°C then remains unchanged when further increases EIS experiment manifests protectiveness passive film reduces CT, variation charge transfer ( R ct ) is keeping potential E pit ). Increasing or raising temperature 80°C enhances...
Effects of TiO 2 on the viscous characteristic mold fluxes for stainless steel were investigated by rotary viscometer, TEM and XRD. The results showed that with increasing amount additive , viscosity solidification temperature could decrease gradually, then increase rapidly. minimum 0.30Pa.s (1300°С ) 1198°С respectively, as was 10mass%. be decreased which played role network modifier, increased precipitation perovskite (CaTiO 3 crystals more than critical value. growth cuspidine...
In order to confirm the source of fouling and corrosion type, process analysis is conducted based on bending tubes hydro-cracking reactor effluent air coolers (REAC) in a refinery. The sediment deposition was analyzed by using CFD technology, critical condition deformation instability determined via stress analysis. On this base, reasons cooler system targeted control measures were determined. results showed that H2S-NH3-H2O existing cooling separation hydrogenation stream, which would...
In this work, the influence of area ratio low corrosion probability (prone to becoming cathode) and high anode) on initiation macrocell a steel bar in simulated pore solution was investigated, along with depassivation mechanism under effect. Meanwhile, set cathode-to-anode (SC/A) actual (pitted) (SC/A′) after were compared. The results reveal that increase SC/A not only increases current density but also promotes drastically. A pronounced positive shift observed at phase due intensified...
Corrosion and sustained casing pressure have serious threats to the integrity of tubing gas well. Researching residual strength corroded has great significance ensure safety The finite element method was used study relationships between corrosion defects size, internal pressure, external axial load. results show that, for with uniform corrosion, defect depth, greater impacts on von Mises equivalent stress tubing, width length little effects it. For pitting while radius effect These...
Basic tundish covering flux is widely used in continuous casting production of high quality steel because good heat insulation function and the properties absorbing inclusions. However, there a serious problem incrustation caused by basic process pouring it could be dramatically influenced crystallization behaviors flux. In paper, time ratio fluxes were investigated temperature electrical resistance furnace single hot thermocouple apparatus. Based on kinetic knowledge experimental results,...
