Feb 21, 2022 · The diameter of the arc on the CPFIC coated rebar increased dramatically, which is attributed to an increase in corrosion resistance due to the addition of the inhibitor. CPFNIC coated rebar had the largest capacitance arc, suggesting that it had the best corrosion resistance among all the coatings tested in the chloride-contaminated environment.
Jan 1, 2024 · The effect of shot peening on microstructure and corrosion of 15–15Ti austenitic steel in liquid LBE at 550 ℃ was investigated. The nanocrystallization and preferential recrystallization were observed, improving the resistance to corrosion and intergranular cracking in LBE.
Jan 1, 2021 · However, Cip in the hierarchical structure of NHACip improves the antibacterial resistance together with enhanced corrosion resistance rendered by the other components. It is because the porous structure of the intermediate HA releases more Cip than a polymeric intermediate layer consequently promoting interactions with bacterial topoisomerase
Corrosion of this rebar caused spalling on a concrete step. The corrosion of reinforcing steel can be a problem in concrete structures. Corrosion of steel produces hydrated iron oxide or rust, which is very expansive. This expansion builds up internal pressure until the concrete fails in the form of spalling. This is a leading cause of concrete
Sep 1, 2022 · At present, the wet-oxygen corrosion degradation of SiC-CMCs limits its application in aero-engine thermal structure components. In order to improve the wet-oxygen corrosion resistance of SiC-CMCs, a series of rare earth compounds with excellent wet-oxygen corrosion resistance were introduced.
Oct 1, 2021 · After 21 days of immersion in Pseudomonas aeruginosa (P. aeruginosa) inoculated media, the results of antibacterial testing and electrochemical characterization in an erosive environment showed that superhydrophobicity significantly inhibited the adhesion of the P. aeruginosa cells and enhanced the corrosion resistance of the composite coating.
Sep 27, 2023 · The microstructure and corrosion anisotropy of the Mg-5Li extruded sheet were investigated in this work. Three distinct samples cut from the normal plane (A), longitudinal plane (B), and cross-sectional plane (C) of the as-extruded sheet were prepared. The microstructure was analyzed using optical microscopy (OM), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The corrosion
Jan 1, 2023 · The ultrafine powder coating panel demonstrates larger modulus of resistance at 0.01 Hz (8.0×10 10 Ω cm 2) than the coarse one (1.4×10 10 Ω cm 2), and boarder plateau of phase angle close to −90° at high frequency domain, which indicate that ultrafine powder coatings have better barrier effect and corrosion protection for the steel than
The same SRB microorganism, isolated from the soil in Shenyang, China, was used for the MIC test [19]. The soil solution was prepared by extracting the soil with a distilled water/soil ratio of 5:1. The physicochemical properties of the dried soil are given in Table 2. Prior to tests, SRB strains were activated in an incubator for 12 h. After that,
Jul 1, 2023 · Abstract. Low-binder eco-efficient concretes and carbon uptake are opportunities for mitigating CO 2 emissions and reaching net zero goals. However, the risk of corrosion induced by carbonation can accelerate.
Jun 1, 2022 · In the previous research of our group [38, 43], it is found that the MMT coating on the surface of AZ31 prepared via hydrothermal method has excellent corrosion resistance. 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
Mar 1, 2024 · 1. Introduction. With the rapid development of high thrust-to-weight ratio aero-crafts, titanium alloys have drawn increasing attention as one of the most popular metallic materials substituting Ni-based superalloys due to their combinational properties of low density, high strength-to-weight ratio, good corrosion resistance, and easy formability as well [1], [2], [3].
Jul 5, 2022 · Titanium alloys have been widely used in the biomedical field due to their high specific strength, good corrosion resistance and excellent biocompatibility [].Nowadays, most of the titanium alloys used in orthopedics or dentistry, such as the Ti6Al4V alloy and the Ti6Al7Nb alloy, are alloyed with toxic Al and/or V elements [2,3], hence their long-term biosafety after implantation raises concerns.
