2018/5/17/ · Proton-exchange membrane fuel cells are one kind of renewable and clean energy conversion device, whose metallic bipolar plates are one of the key components. However, high interfacial contact resistance and poor corrosion resistance are still great challenges for the commercialization of metallic bipolar plates. In this study, we
The paper presents results from the investigations on the corrosion behavior of mild steel (0.17 %C) in water solutions of liquid mineral fertilizer "MAXGROW" at different concentrations (0.2, 0.4, 0.6, 1.0 % vol. and concentrate) and
2018/11/10/ · The polarization resistance values were used to calculate the inhibition efficiency (η %) via the expression [60]: (1) η (%) = 1-R p 0 R p i × 100 where R p o is the polarization resistance of steel reinforcement (in Ω.cm 2) in the absence of EG/AgNPs and R p i is the polarization resistance of steel reinforcement (in Ω.cm 2) in the
1972/9/1/ · Laboratory and field studies have been undertaken to establish the corrosion risks associated with the storage of fertilizer solutions in mild steel vessels. The importance of phosphate in bringing about the formation of protective films in both nitrogenous and other grades is demonstrated.
2022/8/1/ · 1. Introduction. Pharmaceutical manufacturing is a source of antibiotic pollution [1], [2].Antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB) in environmental media can be promoted under antibiotic selective pressures caused by such pollution, in turn contributing to risk of accelerated resistance development and
2020/10/1/ · 1. Introduction. Tylosin, a macrolide antibiotic that is synthesised by microorganisms, is extensively used as a feed additive to prevent and treat diseases caused by bacteria (e.g. Gram-positive bacteria), and promote the growth in the livestock industry [1].However, each ton of tylosin generates more than 10 tons of tylosin fermentation dreg
2024/3/1/ · The use of fillers to enhance the corrosion protection of epoxy resins has been widely applied. In this work, cerium dioxide (CeO 2) and benzotriazole (BTA) were introduced into an epoxy resin to enhance the corrosion resistance of Q235 carbon steel.Scanning electron microscopy results indicated that the CeO 2 grains were rod-like
Corrosion of metal products can seriously affect their reliability. The application of coatings is the most widely used method of corrosion protection due to the desire for easy application and low cost. Most of the present corrosion-resistant coatings are solvent coatings. Due to the high content of volatile organic compounds, the use of solvent coatings is restricted.

2019/1/10/ · Pretreatment is needed before processing fertilizer equipment. To remove the oxide and rust on the surface of steel, it is necessary to use sand blasting machine to remove the surface and clean the surface thoroughly. After cleaning the equipment, the surface should be clean, without any foreign matter. After the removal of foreign bodies
2013/5/15/ · A new type of corrosion-resistant steel consisting of ferrite and bainite phases was developed for cargo oil tanks of crude oil tankers. The corrosion rate of this new steel was 0.22 mm/a, which was equivalent to ca. 1/5 of the criterion (≤ 1 mm/a) for corrosion-resistant steels. The composition and element distribution of the corrosion
2024/2/7/ · The development of superhydrophobic materials have demonstrated significant potential in the realm of corrosion protection for aluminum alloy (Al alloy) surfaces. However, the limited mechanical stability of superhydrophobic surfaces has impeded the rapid advancement in this field. In this research, we synthesized an aluminum phosphate
Sustainability of metals and alloys in construction. P. Lambert, in Sustainability of Construction Materials (Second Edition), 2016 6.3.1 Ferritic stainless steel. Ferritic stainless steels are magnetic, non-heat-treatable steels that contain 11–30% chromium but little or no nickel. They are typically employed for nonstructural applications where there
Abstract. Laboratory corrosion tests were conducted on aluminum, carbon steel, chromium, and chromium-nickel stainless steels to evaluate their suitability as constructional materials for storage, transport, and applicator tanks for “nitrogen” and “complete-mix” liquid fertilizers. Two types of corrosion tests were conducted: (1) Partial immersion of small specimens of
