“…Based on previous research [5] It is very clear that the corrosion rate is strongly influenced by environmental factors, pH, pressure time and temperature. Environmental factors in seawater are not only influenced by salinity, oxygen dissolved and marine biota but also by the content of chemical elements caused by the mining process and waste disposal into the sea.…”

Corrosion hazards in marine environmental construction have been studied. ASTM A36 can be widely used in various industrial sectors and oil extracted offshore. The main objective of this study is to analyze the influence of variation immersion time to corrosion behaviour ASTM A36 by using seawater from Bangka Barat Regency, Bangka Belitung Islands as a corrosive media by performing Brinell hardness test, measurement of weight loss and corrosion rate, and and confirm the data obtained with the formed of microstructure. The results revealed that immersion time of 144 hours produced the highest corrosion rate of 27.97 Mpy and but has the lowest hardness number 136,924 BHN. Microstructural observations found the presence of brownish yellow and black (magnetic Fe3O4) corrosion patterns increased along with the increasing immersion time due to the lack of oxygen concentration during the specimen corrosion process.

“…Steel is a crucial industrial material used for many years ago to manufacture pipes, machinery, structures, and tools; unfortunately, its degradation occurs due to corrosion, a significant problem that generates costly economic losses and irreversible damage [1]. Therefore, preventing and controlling this phenomenon is essential when developing a monitoring or maintenance plan.…”

Abstract. In the present research work, the corrosion inhibition capacity of a liquid extract based on Citrus X-Latifolia leaves was evaluated as a green inhibitor that complies with a natural, economical, and environmentally friendly option. The tests were carried out on a carbon steel AISI 1045 exposed to an acid corrosive medium of 10 mL H2SO4 (0.5 M) to which various concentrations of the extract were dosed as follows: 40, 80, 120, 160, 200, 240, 280, 320, 360 and 400 ppm under standard conditions. Characterization by FT-IR was carried out to detect functional groups of the extract. The inhibitory behavior was recorded by electrochemical techniques (Tafel polarization and EIS). Finally, optical microscopy was used to evaluate the corrosion morphology. The results reveal that the adsorption of the extract molecules on steel follows the behavior of a Langmuir isotherm, reaching a maximum efficiency of 89 % with a concentration of 400 ppm. Finally, an evident change in the surface morphology of the steel sample is observed, thus reducing the pitting corrosion attack on AISI 1045 steel. Resumen. En el presente trabajo de investigación se evaluó la capacidad de inhibición de la corrosión de un extracto líquido a base de hojas de Citrus X-Latifolia como inhibidor verde que cumpla como una opción natural, económica y amigable con el medio ambiente. Los ensayos se realizaron sobre un acero al carbono AISI 1045 expuesto a un medio ácido corrosivo de 10 mL de H2SO4 (0,5 M) al que se dosificaron diversas concentraciones del extracto: 40, 80, 120, 160, 200, 240, 280, 320, 360 y 400 ppm en condiciones estándar. Se realizó una caracterización por FT-IR para detectar los grupos funcionales del extracto. El comportamiento inhibitorio se registró mediante técnicas electroquímicas (polarización de de Tafel y EIS). Finalmente, se utilizó microscopía óptica para evaluar la morfología de la corrosión. Los resultados revelan que la adsorción de las moléculas del extracto sobre el acero sigue el comportamiento de una isoterma de Langmuir, alcanzando una eficiencia máxima del 89 % con una concentración de 400 ppm. Finalmente, se observa un cambio evidente en la morfología superficial de la muestra de acero, reduciéndose así el ataque de corrosión por picaduras en el acero al carbono 1045.
