The low corrosion resistance of aluminum alloy materials in chloride environments limits their application light metal structural components. In this study, 434 stainless steel (SS) powders with different numbers scan layers were deposited on T6061 using high-velocity oxygen fuel (HVOF). Tafel curve, electrochemical impedance spectroscopy (EIS), salt spray, and galvanic tests employed to investigate the comprehensive behavior SS coatings a chlorine environment. results showed that porosity decreased as scanning layer increased. A lower slowed penetration corrosive solution led an enhanced long-term attacks immersion spray corrosion. On basis, preferred SS4 sample iron screw composition system was subjected corrosion, its electric current intensity (5.11 × 10−5 A) two orders magnitude than (9.14 10−3 A), well presenting better anti-corrosion behavior.

Statistical optimization and electrochemical analysis of gambir extract as a corrosion inhibitor for SS-316 in hydrochloric acid

Case Studies in Chemical and Environmental Engineering, Journal Year: 2024, Volume and Issue: 10, P. 100891 - 100891

Published: Aug. 9, 2024

The anti-corrosive properties of Gambir extract on SS-316 stainless steel were studied. It was found that the addition in HCl solution decreased average corrosion current density (I_corr) compared to blank solution. response surface methodology plot showed I_corr increased with increasing concentration and contact time, but higher concentrations extract, indicating its effectiveness inhibiting even under harsher conditions. Surface characterization confirmed formation this protective layer, while FTIR analysis identified main functional groups involved metal-inhibitor interaction.
