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
Mar 1, 2023 · 1. Introduction. High-entropy alloys (HEAs) contain five or more elements at relatively high concentrations (5–35 at.%) [1, 2].Owing to their unique high-entropy, sluggish diffusion, lattice distortion, and cocktail effects [[3], [4], [5]], HEAs exhibit excellent properties not exhibited by traditional alloys, such as high hardness [6], high strength [7], corrosion resistance [8], and high
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
Mycorrhizae improved resistance most strongly when plants were fertilized with a phosphorus rich, organically derived fertilizer. In both experiments, increased resistance was correlated with changes in the plant's foliar nitrogen content. Synthesis and applications.

Feb 11, 2021 · Corrosion is an electrochemical phenomenon. It can occur via different modes of attack, each having its own mechanisms, and therefore there are multiple metrics for evaluating corrosion
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
Dec 6, 2016 · Magnesium (Mg) and its alloys have been suggested as revolutionary biodegradable materials. However, fast degradation hinders its clinic application. To improve the corrosion resistance and biocompatibility of Mg–Nd–Zn–Zr alloy (JDBM), magnesium–aluminum-layered double hydroxide (Mg–Al LDH) was successfully introduced into Mg(OH)2 coating by hydrothermal treatment. The anions in the
Dec 1, 2022 · 2.2. Electrochemical test. Electrochemical tests were carried out on an electrochemical workstation (CS 350 H, CorrTest) using a conventional three-electrode system, wherein a platinum plate was used as the counter electrode, a saturated Ag/AgCl electrode was used as the reference electrode, and the sample was used as the working electrode.
Jun 13, 2023 · Fertilizers can encourage corrosion through direct contact or by passing corrosive gases such as chloride into the interior environment. Moisture can render fertilizer worthless as well as encourage building corrosion, so humidity is an important consideration—even more so if the building is located in a coastal area where the air is not only
Feb 15, 2023 · 1. Introduction. The 316L stainless steels are often used in petroleum, chemical, and marine equipment because of the superior corrosion resistance [1].Nowadays, the laser additive manufacturing technology has aroused the interest of researchers in the fields of biomedical equipment, marine equipment and remanufacturing because it can produce parts with individuality and complex shapes and
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
