... steels (P91 and SS304) consists of an (Fe,Cr)₃O₄ spinel layer. Conversely, the oxide scale on the highly alloyed Alloy 33 consists of a multi-layered outer Ni-rich oxide, middle Ni-Cr-Fe spinel, and inner Cr-rich oxide. The thicknesses of the oxide layers formed on P91, SS304...

...EN 10028-2 is used in piping and casing. Its benefits are low cost and the good fabricability of the material. Carbon steel is considered having uniform corrosion in geothermal systems and thick walls are needed to account for thinning. When the coupon has been exposed in the wellhead for 3 months...

...Marine Cathodic protection Steel Fouling Current shielding INTRODUCTION Civil infrastructure immersed in natural waters is subject to physical, chemical and biological interactions with the environment that can result in material degradation. Among the naturally-occurring phenomena, corrosion...

... of marine-grade carbon steels and stainless steels (UNS G10180, UNS S30400 and UNS S31603) were ground to multiple finishes (80 grit, 600 grit and 0.05 μm) to achieve various surface roughnesses. The cylindrical test coupons were immersed in biologically active seawater off the coast of Southern California...

... have been reported by several authors. ^{5 , 6 , 7} However, the use of injecting seawater (water flooding) as a means of enhancing oil recovery significantly increases the possibility of corrosion failure of the tubulars as it increases the risk of water wetting the steel surface. ⁷...

...Additional measurements have been performed in a cyclic corrosion test and under field conditions. The main aim of this work was to use the ER techniques to better understand the effect of chloride and wet/dry transitions on the corrosion of steel and zinc respectively. EXPERIMENTAL PROCEDURE...

... of different metals ranging from carbon steel via stainless and duplex steels to titanium in a copper containing artificial geothermal water, simulating the conditions in the Northern German Basin, using electrochemical measurements and exposure tests. While carbon steel exhibits copper deposition (scaling...

... measured and associated with microstructure and hardness profile. Results showed that HIC susceptibility is related to the hardness. Regions with higher hardness had a higher tendency for crack initiation. hydrogen steel flexible pipe hydrogen sulfide INTRODUCTION Flexible pipes may be exposed to high...

... inhibitors which are responsible for inhibition of steel in acidic solution. The framework consists of modules like data preprocessing, descriptor selection and model building. A robust predictive model for multiple class of corrosion inhibitors was developed using advanced machine learning algorithm...

... to sufficiently soften the base material through thickness to reduce the welding loads and tool wear while not excessively tempering the steel mechanical properties outside of the weld zone, in the heat affected zone (HAZ). The targeted maximum pre-heating temperature at 25mm away from the weld centerline was 600...

...As mentioned above Tafel slope is decided from the actual polarization curve and the corrosion rate is calculated by extrapolation method, it was confirmed that CIPE method was very useful for monitoring various corrosion rates of steel in concrete. ^{3 , 4} However there is little actual...

... sensitive to oxygen and nitrogen contamination such as low alloy steels, martensitic steels, stainless steels and nickel alloys. ⁵ Additionally, aluminum and titanium alloys have been deposited using laser wire based additive processes. Wire arc additive processes Wire arc additive...

... polymerization of aniline in solutions of two different inorganic acids. The corrosion tests were carried out on carbon steel substrates coated by alkyd coatings (using frame film applicator, one-coat application) containing the anticorrosion pigments 0.5 mass% of these composites in comparison to coating...

... E_a⁰ from E_a¹. When η_a¹ was 10 mV or more, the steel surface was evaluated as “Passivation” or “the corrosion rate was less than 1 mA m^-2 ”. 2-2) When η_a¹ was less than 10 mV, evaluation proceeded to the step (3). Evaluation...

... streams are dominated by contaminated steel cladding with Zr and small amounts of noble metal fission products from the fuel. The predominant alloy phases that form are FeCrMo-based intermetallics that host Tc and FeZrNi-based intermetallics that host actinide fuel wastes. An experimental protocol...

... samples. Metal dollies were glued to the surface of the coated coupon using a two-part epoxy and allowed to set for 24 hours. The perimeter around the fastened dolly was then scored down to the steel substrate prior to testing with a pull-off adhesion tester ⁸ . The coating pull-off strengths...

... uncertainties on the performance of these bolts using a Bayesian probabilistic approach. The paper also discussed conceptual approaches to managing the performance of bolts. Bolting Hydrogen Embrittlement Probabilistic Assessment Steel CRA INTRODUCTION There are numerous flanged joints in offshore oil...

... chromium and minor iron and nickel oxides. The mechanism of the defective passive film formation is discussed. The increase of the applied potential is considered to be a reason for the change in passive film stability. Steel Passive film X-ray photoelectron spectroscopy INTRODUCTION The passivity...

.... The stress corrosion cracking behavior was measured by slow-strain rate tests with accelerated anodic and cathodic reactions. The results indicated that the UNSM treatment has a significant effect on the corrosion condition, whereas no effect appeared in the hydrogen embrittlement. weld steel corrosion...
