Simulated oil well water (SOWW) is conceded out by pipelines made of several alloys, for instance mild steel L80. These alloys may simulated oil well water undergo corrosion owing to presence of various aggressive ions present in SOWW. To prevent this several inhibitors have been used. Inhibition of corrosion of L80 alloy pipeline carrying simulated oil well water by succinic acid has been evaluated by electrochemical studies such as polarization study and AC impedance spectra (EIS). Polarisation study reveals that in the presence of inhibitor linear polarization resistance increases and corrosion current decreases. AC impedance spectra reveal that in presence of succinic acid, RT value increases, impedance value increases, phase angle increases and Cdl value decreases. The present study reveals that when succinic acid is added to simulated oil well water, the corrosion resistance of L80 alloy increases. It implies that succinic acid may be added to simulated oil well water flowing through pipe line made of L80 alloy.

“…% of SiC aluminium composite sample immersed in H 2 SO 4 acidic for 56 hours. Furthermore, this pitting corrosion can be decreased and maintained by giving proper painting and surface treatments that form a coating on the aluminium surface [32][33][34]. Corrosion can also be controlled by cleaning the surface of the aluminium using mild alkaline and acidic detergents.…”

The main objective of this investigation is to study the microstructural features and evaluate the tensile strength, hardness, and acidic corrosion resistance of liquid metal stir casted aluminium-silicon carbide (Al-SiC) composite. As reinforcement for the Al alloy matrix, SiC particles were added to the matrix in the percentages of 0%, 10%, and 20%. The microstructure of Al-SiC composite was studied using optical microscope. The effect of addition of SiC particles on tensile strength and hardness of Al-SiC composite was analyzed.. There were significant improvements in tensile strength and hardness for Al–SiC composite reinforced with 20% SiC particles compared to unreinforced Al–SiC composite, and those improvements were of 14.70% and 26.88%, respectively. The evolution of harder SiC islands in the ductile matrix of aluminium alloy reinforce the Al-SiC composite which enhances the strength and hardness of Al-SiC composite. A weight loss method was used to determine corrosion rate. The samples of Al-SiC composite material were immersed in HCl, HNO3, and H2SO4 solutions for immersion times of 30 hours, 56 hours, and 80 hours. It was found that the weight % of reinforcement had the largest contribution to corrosion rate with 49.86% to that of acidic solution with 29.88%, followed by immersion time with 8.85% and acidic solution with a contribution of 29.88% to the corrosion rate. The Al-SiC composite developed using 20 wt. % of SiC particles showed higher corrosion rate due to the interfacial region formed due to the addition of greater wt % SiC particles to the pure alloy.

“…Several studies have used plant extracts as additives, such as cauliflower [ 12 , 13 ] and Leucaena leucocephala [ 14 ]. Moreover, the use of natural products from the flora and fauna is believed to be non-harmful, non-toxic, biodegradable, and readily available for mass production [ 15 ]. The bioactive compounds in the plants, such as alkaloids, flavonoids, and gallic acids, are believed to retard the corrosion process.…”

With the trend for green technology, the study focused on utilizing a forgotten herb to produce an eco-friendly coating. Andrographis paniculata or the kalmegh leaves extract (KLE) has been investigated for its abilities in retarding the corrosion process due to its excellent anti-oxidative and antimicrobial properties. Here, KLE was employed as a novel additive in coatings and formulations were made by varying its wt%: 0, 3, 6, 9, and 12. These were applied to stainless steel 316L immersed in seawater for up to 50 days. The samples were characterized and analyzed to measure effectiveness of inhibition of corrosion and microbial growth. The best concentration was revealed to be 6 wt% KLE; it exhibited the highest performance in improving the ionic resistance of the coating and reducing the growth of bacteria.
