May 1, 2023 · The long-term corrosion resistance test evidenced that the healed composite coating has effective barrier performance and long-term corrosion resistance, and the low-frequency impedance was still above 10 8 Ω·cm 2 after 50 days of immersion. Corrosion inhibitors and disulfide bonds jointly contribute to effective corrosion resistance by
Apr 18, 2023 · The significantly lower I corr value of 8.92e-08 μA (a order of magnitude less than reinforcements without coating) and the highest impedance value and polarization resistance, implied more corrosion resistance for OPR coated rebars than others. The characterization of the surfaces revealed the smooth morphology of the OPR coating.
Dec 4, 2017 · Composting is an efficient way to convert organic waste into fertilizers. However, waste materials often contain large amounts of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) that can reduce the efficacy of antibiotic treatments when transmitted to humans.
Apr 15, 2024 · The enhanced localized corrosion resistance in AM stainless steels has been widely attributed to refinement of pit initiating MnS inclusions. Even though the mechanism of pit initiation around the MnS inclusions in stainless steels is different from that of nitrides in Ni-alloys, both share the trait of being preferential pit initiation sites
Oct 12, 2023 · Microbial compost plays a crucial role in improving soil health, soil fertility, and plant biomass. These biofertilizers, based on microorganisms, offer numerous benefits such as enhanced nutrient acquisition (N, P, and K), production of hydrogen cyanide (HCN), and control of pathogens through induced systematic resistance. Additionally, they promote the production of phytohormones
Feb 1, 2019 · The enhanced corrosion resistance is understood by the corrosion behavior and electrochemical properties of the Cu@Gr flakes and bulk Gr/Cu composites. Our results have implications for graphene's performance in a wide range of applications, and shed light on producing structural/multi-functional metal matrix composites for many practical
enhanced corrosion resistance large scale composting Large-Scale Organic Materials Composting - NC State Extension 2 days ago · Once they’re converted into compost, organic wastes—which are the compostable portions of the solid waste stream—can be used to mulch landscaping, enhance crop growth, enrich topsoil, and provide other benefits.
Feb 1, 2024 · In addition to E corr and i corr, polarization resistance (R p) was calculated using the Stern-Geary [49] equation: (1) R p = β a β c 2.303 i corr (β a + β c) where β a is the anodic Tafel slope, and β c is the cathodic Tafel slope. R p indicates the resistance of a material to general corrosion, and higher values reflect a superior
Jan 25, 2018 · With increasing the laser scanning speed, the corrosion resistance of CFs/Ni-based coatings gradually increases due to high corrosion resistance of CFs and decrease in the amount of precipitated M 7 C 3 and M 23 C 6 carbides adjacent to grain boundaries. 3. CFs/Ni-based coatings show better wear resistance than Ni-based alloy coatings.
May 10, 2023 · Generally, the corrosion of magnesium (Mg) and its alloys is accompanied by hydrogen production, which can cause gas pockets and severe biological problems when they are used as implants. Germanium (Ge) as an alloy additive can moderate the cathodic reaction of Mg alloys and significantly delay the corrosion of Mg alloys via the cathode “poisoning” effect. In this study, the influence of
Aug 18, 2021 · B-type carbonate apatite (CAp) coatings were formed on as-cast and T4-treated Mg-xZn (x = 1, 5, and 7 wt %) alloys containing various sized Zn-rich second phase to improve the corrosion resistance and biocompatibility. The CAp coating grew uniformly on the alloys with a thickness of 1.1–1.3 μm and did not show cracks or pores on 30 μm-sized second-phase particles. The CAp coating retarded
Dec 1, 2017 · Results show that the epoxy coating with superior corrosion resistance can be obtained by addition of the mixture of surface modified GO and NC particles. Table 1 . The impedance parameters extracted from modeling (R(RQ) model) of EIS results for the epoxy coatings applied on the steel sheets, immersed in 3.5 wt% NaCl solution for 2, 4 and 8 weeks.
Jun 1, 2022 · Therefore, the corrosion resistance of GS/MMT coating was tested. Hereby the GS concentration used in the corrosion resistance tests is set at 2.5 mg/ml on the basis of our previous study. 2.3.1. Change in pH. The immersion test was used to measure the pH of the dulbecco's modified eagle medium (DMEM) during corrosion.
Feb 1, 2023 · In this EEC, R s represents the resistance of RM solutions, R f stands for the resistance of steel passive films and CPE f is a constant phase element of passive film capacitance. R ct is the charge transfer resistance of carbon steel, and CPE dl represents the double layer capacitance, which is caused by an inhomogeneous current flow [42], [52].
