Sep 27, 2023 · The short-term corrosion resistance of Mg(Cu)-LDH/AZ91D was enhanced significantly with a lower corrosion current (3.98×10 −6 A/cm 2) and a larger impedance arc radius, than the Mg alloy substrate. The improvement of corrosion resistance was attributed to the effect of the LDH barrier. (2)
Jan 29, 2021 · Silt has poor engineering properties, and lime and/or fly ash are widely used to treat silt. However, very few studies could be found to investigate the water resistance and compressibility of lime and fly-ash mixtures (lime–FA) solidified silt. This paper investigated the unconfined compressive strength (UCS), water resistance and consolidation properties, and the microscopic
Oct 15, 2023 · During composting, pH is a crucial indicator of microbial activity and population composition [51].The variation in pH values during composting is also shown in Fig. 1.At the start of the composting process (Day 0), the pH of BPA pile mixture was 4.3, known to be due to food waste acidification, which produces organic acids as well as some volatile acids of low-molecular-weight
May 15, 2024 · Based on the interpretable machine learning design strategy proposed in this work, the KDA alloy achieved synchronous improvement in strength, toughness, and stress corrosion resistance, achieving UTS = 760 ± 4 MPa, K IC = 34.9 ± 0.3 MPa·m 1/2, and ISSRT = 13.3 % ± 1.7 %. The research in this work breaks through the challenges of rapid

Sep 22, 2023 · The silt sample was classified as poorly graded silt with a predominance of silt, with an average non-uniformity coefficient (Cu) of 3.95 and a coefficient of curvature (Cc) of 0.972. Therefore, the Yellow River alluvial silt sample does not meet these criteria and requires modification if it is to be used as a subgrade material.
Aug 11, 2020 · Here we show, by engineering crystallographic configurations upon metal matrices adjacent to their passive films, we obtain great enhancement of corrosion resistance of FeCr15Ni15 single
modified yellow river silt-based cementitious material was significantly increased when the water glass dosage was 12 wt% (s=1.8)) and the slag dosage was 40%, and its 90-day maximum compressive strength could M reach 53 MPa. Key words: yellow river silt; alkali-activation; blast-furnace slag; compression molding

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
Commercial composting involves the controlled decomposition of organic materials such as food scraps, yard trimmings, and agricultural residues on a large scale. Unlike traditional backyard composting techniques that require weeks or months to produce usable compost, commercial operations employ advanced technologies and processes to speed up
River Silt (126) SPECIFICATIONS Plank Size. 7.36" x 48" (187mm x 1227mm) 10-Year Commercial River Silt - 126. Color also available in RigidCORE Keystone
Feb 1, 2024 · However, the incorporation of an excessive amount of CNCs (i.e., 0.8 and 1.0 wt%) significantly compromised the corrosion resistance of epoxy coatings due to aggregation-induced coating defects. Overall, this study provides a facile and green strategy for corrosion resistance improvement of waterborne epoxy coatings.
Jul 8, 2022 · This study explores the effect of surface re-finishing on the corrosion behavior of electron beam manufactured (EBM) Ti-G5 (Ti-6Al-4V), including the novel application of an electron beam surface
