Nov 1, 2022 · The corrosion and wear behaviors of materials are usually sensitive to the microstructural features. In the current work, a novel strategy using laser surface remelting (LSR) to modify the surface microstructure of a precipitate-hardened magnesium alloy was proposed to synergistically enhance the corrosion and wear resistances.
Mar 1, 2024 · The results indicated that the composite epoxy resin with the coaddition of CeO 2 and BTA could effectively block the direct contact between the corrosive medium and the steel substrate, leading to the enhanced corrosion resistance of the substrate [48]. 3.2. Corrosion resistance mechanism of the coatings
Jun 2, 2021 · In this paper, farming fertilizer was used as the corrosive media to study the surface morphology, components, and chemistry of Ni coatings after electrochemical corrosion. After electrochemical corrosion, some fertilizer was adsorbed on the surface of Ni coatings, resulting in a layer of flocculent corrosion products on the surface. The electrochemical micro-corrosion characteristics showed
Oct 1, 2013 · Fig. 3 a and b shows the TEM micrographs of the as-received AZ61 alloy and HRDSR 3SP, respectively. While the as-received AZ61 alloy has the heterogeneous microstructure composed of mixture of large grains with deformation bands and twins (Fig. 3 a) and large grains with low dislocation density, HRDSR 3SP has the fairly homogeneous microstructure composed of very fine grains often with a high
Dec 1, 2020 · Equiatomic CoCrFeMnNi HEA was successfully fabricated by selective laser melting. •. The composition uniformty and multi-scale microstructure characterization of the SLMed HEA were studied. •. The SLMed CoCrFeMnNi HEA had better corrosion resistance than the as-cast CoCrFeMnNi HEA in NaCl solution. •.
Aug 8, 2019 · Polyetheramine (D230), an epoxy curing agent, was grafted on graphene oxide (GO) surfaces, which can be stably dispersed in a waterborne curing agent for more than 8 months. Waterborne epoxy coatings reinforced by D230-functionalized GO (DGO) were prepared on carbon steel surfaces. According to the electrochemical impedance spectra, the impedance modulus at 0.1 Hz remained at 2.2 × 109 Ω
Sep 27, 2023 · Previous researches reported that the MgAl-LDH could be introduced onto the surface of Mg alloys by hydrothermal treatment, resulting in enhanced corrosion resistance [15, 16]. In other research, 8-hydroxyquinoline (8HQ)-intercalated MgAl-LDH was coated on the AZ31, which enhanced corrosion resistance, a feature ascribed to the Cl − and HQ
