Effects of CO2 and H2S on corrosion of martensitic steels in NaCl(aq) at low temperature
(Nace International, 2016)
Corrosion studies were conducted for martensitic carbon steels in brine solutions at 4 °C and 10 MPa (1450 psi), which simulated the subsurface environments encountered in Arctic drilling. Three environments with a 5 % wt. ...
The effect of alcohol on the passivation of Al alloys in 1 N H 2 SO 4 solution
(Pleiades Publishing, Ltd, 2010)
In this study, the influence of different alcohol on the passivation of aluminium alloys have been investigated by using current potential curves. Experimental results show that the addition of alcohol in H2SO4 solution ...
Corrosion behaviors of hydroxyapatite coated by electrodeposition method of Ti6Al4V, Ti and AISI 316L SS substrates
(Pleiades Publishing, Ltd, 2013)
Electrodeposition method was used to obtain hydroxyapatite (HAP) coatings on Ti6Al4V, Ti and AISI 316L SS substrates. Electrodeposition solution is prepared as Ca(NO3)2 ⋅ 4H2O and (NH4)H2PO4. Additionally, three different ...
Effects of H2S and CO2 on Cement/Casing interface corrosion integrity for cold climate oil and gas well applications
(The Electrochemical Society, 2016)
Low-temperature corrosion relevant to oil and gas wells was investigated. Casing cement was exposed to brine in contact with CO2 at 4 °C and 10 MPa. Pore water was extracted from wet cement using a die press, and a cement ...
The effect of polypyrrole and nickel + polypyrrole coatings on corrosion behaviour AISI 304 stainless steel
(Pleiades Publishing, Ltd, 2015)
Polypyrrole (PPy) and nickel + PPy (Ni + PPy) coatings have been occured on AISI 304 stainless steel (304 SS) surface by cyclic voltammetry technique in aqueous oxalic acid solutions and as the supporting electrolytes was ...
Corrosion of 13Cr steel at the Cement/Casing interface in CO2/H2S environments at 4, 85 and 200 °C
(Nace International, 2018)
A study was carried out to investigate corrosion at the cement/casing interface for 13Cr casing steel. Cement simulated pore solution (CSPS) was developed by exposing cement pieces to 5% NaCl at 100 °C and 10 MPa in ...
The examination of Afyonkarahisar's geothermal system corrosion
(ASM International, 2013)
Corrosion and scaling of metal surfaces are the major problems caused by geothermal fluids when metallic structures are used. This article describes a study of corrosion and scaling problems in the Afyonkarahisar Geothermal ...
Electrochemical corrosion of Ti6Al4V, Ti and AISI 316L SS after immersed in concentrated simulated body fluid
(Pleiades Publishing, Ltd, 2016)
The biomimetic method is used to obtain hydroxyapatite (HAP) coatings on Ti6Al4V, Ti and AISI 316L SS substrates. These substrates with different pretreatment surface operations (HNO3, anodic polarization, base-acid) were ...
Corrosion behavior of 13Cr casing steel in cement-synthetic pore solution exposed to high pressure CO2 and H2S
(The Electrochemical Society, 2015)
The electrochemical corrosion behavior of grade L-80, type 13Cr casing steel was investigated in cement-synthetic pore solution (CSPS) exposed to CO2 and H2S using in-situ electrochemical methods and ex-situ surface analyses ...
Corrosion inhibition of st37 steel in geothermal fluid by quercus robur and pomegranate peels extracts
(Pleiades Publishing, Ltd, 2015)
Plant extracts have become important as an environmentally acceptable, readily available and renewable source of wide range of inhibitors. Tannins, a class of natural, non toxic and biodegradable polyphenolic compounds, ...
