Scale deposit Corrosion products Morphology Under-deposit corrosion Microorganism induced corrosion INTRODUCTION Water injection is an important means to increase oil production...

...The investigation was based on the idea that some corrosion products could be present in the pores of the sample. The method chosen for high entropy alloy production was mechanical alloying followed by pressing and sintering. The consolidation performed by classical uniaxial pressing and sintering...

... environment revealed corrosion products contains sulfur and oxygen. The low corrosion rate obtained for this HEA suggest that this alloy could be a good candidate for further coating components working in geothermal steam corrosion geothermal environment multicomponent alloys microstructure corrosion...

... to measure the corrosion rate of the AlCrFeNiMn high entropy alloy. The results showed that the uniform corrosion rate was quite high, on average 3 mm/year. Microstructural and chemical composition analyses of the specimen after the exposure in the geothermal environment revealed corrosion products...

... of films formation additivity i.e. when inhibitor film has no any influence on structure or properties (include protective one) of CP film. There are 3 method modifications which considered in the paper. Abstract The film of corrosion products (CP) often has certain protective properties and leads...

... and morphology in CO₂ and H₂S-containing systems. However, from the perspective of pit initiation and propagation in CO₂-saturated environments, the extent to which in-situ pH of solutions and the presence of corrosion products influence localized attack is still...

... were cleaned in an ultrasonic bath for 1 min to remove soft corrosion products. The coupons were cleaned as per ASTM G 01 ³⁰ and ASTM G 31 ³¹ . The mass loss of the coupons was determined according to the procedures described in ASTM G 16 ³² and ASTM G 46. ³³...

... installations. Results from mineral-, gas-, and brine analysis strongly indicated two different corrosion processes to take place in the production well casing. The first process (1) can be attributed to anaerobic steel corrosion, as indicated by the corrosion products hydrogen (H2) in the gas phase (up to 8...

...Abstract The capability of iron pipe corrosion products in active drinking water systems to concentrate metal ions, such as Pb, Sr and V from treated drinking water and mechanisms that can cause consumer exposures and releases back into the environment will be presented. We propose that sorption...

.... After the experiment, the sessile SRB were enumerated by serial dilution and optical microscopy, scanning electron microscopy, mass loss and laser profilometry were used to identify corrosion products, bacterial cell and corrosion rate. Both mass loss and localized pitting corrosion were two and three...

...The aim of this work is to investigate the corrosion products formed at different pH values. For this reason salt spray tests based on DIN EN ISO 9227 ¹¹ , ⁽¹⁾ were performed. The only variable that was varied was the pH value of the sprayed solutions. After the corrosion...

... Diffraction (XRD) technique was used to identify deposits in SRUs. The accumulation of these materials cause major problems and cause plants to shut down. It has been observed that the samples collected from the condensers are sulfates (ammonium, iron, sodium iron) and corrosion products. The presence...

... for all species involved in the corrosion reaction. This film undergoes a cyclic process of growth, cracking, and delamination to develop an iron sulfide corrosion product layer. The amount of iron sulfide retained on the steel surface depends on the layer formation rate and the layer damage rate...

... (Ju’aymah and Shedgum). The Research and Development Center (R&DC) has helped the plant engineers to overcome the problems by identifying the nature and source of compounds (e.g., corrosion products, formation materials and scale deposits). The boiler consists of a furnace, boiler tubes, steam drum, mud...

... and temperature using conventional thermodynamic models) and the predicted iron saturation levels. Corrosion products formed during hydrotest are conservatively considered to be those resulting from the complete reduction of the amount of dissolved oxygen present in the hydrotest water, assuming...

... environmental situations. Two of the copper carbonate minerals, azurite [2CuCO₃.Cu(OH)] and malachite [CuCO₃.Cu(OH)₂], are important both as pigments and as corrosion products. This example focuses on the use of these copper carbonates as pigments during the Spanish Baroque...
