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 ...
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 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 ...
Methanol oxidation on Aluminium-Copper-Silicon alloys coated with polyprrole
(Pleiades Publishing, Ltd, 2012)
Methanol oxidation on the aluminum copper silicon alloys which are coated with polyprrole were investigated in 1 N H2SO4 by using electrochemical method. For this purpose, first the current density potential curve of ...
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 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 ...
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 coating of hydroxyapatite ( HAP ) on 316L stainless steel and Ti6Al4V alloy use by Sol-Gel method
(Afyon Kocatepe Üniversitesi, 2010)
In this research, hydroxyapatite (HAP) coatings have been coated on Ti6Al4V alloy and 316 L stainless steel substrates by sol-jel method. (NH4)H2PO4 is taken as P precursor and Ca(NO3)2.4H2O is taken as Ca precursor to ...
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 ...
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 ...
