Failure Analysis of Corrosion-Induced Perforation in B10 Copper-Nickel Alloy Pipelines
Published 2024-12-01“…The B10 copper-nickel alloy pipeline used for seawater transportation on a certain platform was found to have corrosion perforation at the weld joint between the elbow and the flange during a shutdown inspection.In this study, the failure mechanism of corrosion perforation was analyzed using macroscopic morphology observation,scanning electron microscopy (SEM),energy-dispersive spectroscopy (EDS),X-ray diffraction (XRD) and metallographic examination.Results showed that “sugar cube”-like intergranular corrosion morphologies were commonly observed at the bottom of corrosion pits on the flange, in erosion-wear areas, corrosion grooves, perforated regions and at the bottom of corrosion pits on the elbow.Locally, a “stepped” exfoliation morphology was observed, where grains were progressively stripped layer by layer.The preferentially corroded grain boundaries formed a circuit, and the surrounded grains were selectively denickelized and dissolved, resulting in grain spalling.The reduced hardness and coarse columnar grain structure of the flange further decreased the material’s corrosion resistance.The corrosion perforation of the copper-nickel alloy pipeline occurred in the erosion-sensitive zones and the weld heat-affected zones with the poorest corrosion resistance.This failure was the result of the synergistic effects of erosion wear, intergranular corrosion and selective dealloying.Enhanced corrosion monitoring is recommended for similar locations in service pipelines.…”

Preparation and Corrosion Resistance of Superhydrophobic Coating on AZ31 Magnesium Alloy
Published 2024-12-01“…The active properties,easy oxidation and poor corrosion resistance of AZ31 magnesium alloy have always been the biggest challenges in its practical application.In order to improve its corrosion resistance, reduce the corrosion rate and prolong its service life, a stable and corrosion-resistant aluminum phosphate-polymethyl methacrylate (AP/PMMA) superhydrophobic coating was prepared on the surface by impregnation method.The microstructure, chemical composition, phase composition and molecular structure of the coating were analyzed by scanning electron microscope (SEM),X-ray energy dispersive spectrometer (EDS),X-ray diffractometer (XRD) and Fourier transform infrared spectrometer (FTIR).Moreover, the hydrophobicity and corrosion resistance were tested by contact angle meter (CA), Tafel curve and EIS.Results showed that with the increase of immersion time, the contact angle (WCA) of the coating increased first and then decreased.The surface contact angle of the coating prepared by the 60 s immersion sample could reach 154.7 °, showing superhydrophobicity.The surface corrosion current density was 2.289 × 10-9 A/cm2, which was 4 orders of magnitude lower than that of the magnesium substrate.The corrosion potential was increased from-0.941 V to-0.735 V after polishing, indicating that the AP/PMMA superhydrophobic coating could effectively improve the corrosion resistance of AZ31 magnesium alloy.…”
