Corrosion behaviour of coatings on 304 steel
(ASIAN PUBLICATION CORPORATION, 2012)
The aim of this study is to determine the corrosion characteristics of 304 steel by the methods of Tafel extrapolation, linear polarization and electrochemical impedance spectroscopy (EIS). The steel surface is covered ...
Electrochemical polymerization of aniline on aluminum electrode from an oxalic acid and H2SO4 solutions
(Pleiades Publishing, Ltd, 2009)
In this study, the polymerization of aniline on Al and Pt electrode was examined by cyclic voltammetry There had been reversible reaction on AI electrode. But on the other hand there had been irreversible reaction on Pt ...
Corrosion behavior of 13Cr casing steel in cement-synthetic pore solution exposed to high pressure CO2 and H2S
(The Electrochemical Society, 2015)
As deeper wells drilled for oil and gas extraction encounter higher pressures, temperatures, and concentrations in the downhole environment, it becomes increasingly important to consider the integrity of the casing that ...
The examination of corrosion behaviors of HAP coated Ti implant materials and 316L SS by Sol-Gel method 1
(Pleiades Publishing, Ltd, 2011)
In this research, hydroxyapatite (HAP) coatings have been produced on Ti, Ti6Al4V alloy and 316L stainless steel substrates by sol–gel method. (NH4) H2PO4 is taken as P precursor and Ca(NO3)2 4H2O is taken as Ca precursor ...
Corrosion behavior of ultra-high strength drilling steel in alkaline brines containing hydrogen sulfide at high temperature
(Nace International, 2016)
In-situ electrochemical measurements were used to study the sour corrosion of ultra-high strength low alloy carbon steel (UHSLA) in alkaline brines at 200 °C. The solutions were buffered with NaHCO3 / Na2CO3 / NaOH to pH ...
Effect of H2S and CO2 on Cement/Casing alloy interface corrosion integrity for cold climate oil and gas well applications
(The Electrochemical Society, 2016)
A study has been carried out to investigate sweet and sour corrosion at the cement-casing interface for offshore oil and gaswells in cold climate. The test solution chemistry was determined by sampling pore water from ...
Electrochemical corrosion behavior of high strength carbon steel in H2S-Containing alkaline brines
(The Electrochemical Society, 2015)
The electrochemical corrosion behavior of high strength low alloy carbon steel API S-135 was investigated using in-situ electrochemical measurements, ex situ surface analyses, and software modeling in the alkaline brines ...
Electrochemical determination of bisphenol a with pencil graphite electrodes modified with Co(II), Ni(II), Cu(II) and Fe(II) phthalocyaninetetrasulfonates
(The Japan Society for Analytical Chemistry, 2016)
Pencil graphite electrodes modified with Co(II), Ni(II), Cu(II) and Fe(II) metallophthalocyaninetetrasulfonates (MePcTSs) were investigated for electrochemical determination of bisphenol A (BPA). Electrochemical performances ...
Corrosion behaviours of hydroxyapatite coated by biometic method of Ti6Al4V, Ti and AISI 316L SS substrates
(ACADEMIA ROMÂNĂ, 2012)
Biomimetic method was used to obtain hydroxyapatite (HAP) coatings on Ti6Al4V, Ti and AISI 316L SS substrates. The solutions were prepared as 1.5xSBF and 3.0xSBF similarly to body fluid (SBF). Additionally, three different ...
