Triazole derivatives as corrosion inhibitors for mild steel in hydrochloric acid solution

Acta Metallurgica Sinica(English Letters) 2009年第4期22卷 247-254页

作者： Fengling XU baorong HOU Institute of Oceanology Chinese Academy of Sciences Qingdao 266071 China Graduate School of Chinese Academy of Sciences Beijing 100039 China

The title compounds 1-（4,5-dihydro-3-phenyl pyridine-1-yl）-2-（1H-1,2,4-triazole-1-yl） ethyl ketones were studied as a corrosion inhibitor in a mild steel in 1 mol /L hydrochloric acid solution using weight loss measurement, potentiodynamic polarization, and electrochemical impedance spectroscopy （EIS）. Results indicated that these compounds had excellent inhibition properties. Polarization curves indicated that the inhibitor behaved mainly as mixed-type inhibitor. The EIS results showed that the charge transfer controlled the corrosion process in the uninhibited and inhibited solutions. Adsorption of the inhibitor on the mild steel surface followed Langmuir＇s adsorption isotherm with negative value of the free energy of adsorption ΔGads^o. The thermodynamic parameters of adsorption were determined and discussed.

Modeling nitrate aerosol distributions and its direct radiative forcing in East Asia with RAMS-CMAQ

引用

Particuology 2013年第3期11卷 256-263页

作者： Xiao Han Meigen Zhang baorong Zhou State Key Laboratory of Atmospheric Boundary Layer Physics and Atmospheric Chemistry Institute of Atmospheric PhysicsChinese Academy of Sciences Xinghua Meteorological Bureau

The geographical and seasonal characteristics in nitrate aerosol and its direct radiative forcing over East Asia are analyzed by using the air quality modeling system RAMS-CMAQ coupled with an aerosol optical properties/radiative transfer module. For evaluating the model performance, nitrate ion concentration in precipitation, and mixing ratios of PMl0, and some gas precursors of aerosol during the whole year of 2007 are compared against surface observations at 17 stations located in Japan, Korea, and China, and the satellite retrieved NO2 columns, The comparison shows that the simulated values are generally in good agreement with the observed ones. Simulated monthly averaged values are mostly within a factor of 2 of the measurements at the observation stations. The distribution patterns of NO2 from simulation and satellite measurement are also similar with each other. Analysis of the distribution features of monthly and yearly averaged mass concentration and direct radiative forcing （DRF） of nitrate indicates that the nitrate aerosol could reach about 25-30% of the total aerosol mass concentration and DRF in Sichuan Basin, Southeast China, and East China where the high mass burden of all major aerosols concentrated. The highest mass concentration and strongest DRF of nitrate could exceed 40 μg/m^3 and -5 Wire2, respectively. It also indicates that other aerosol species, such as carbonaceous and mineral particles, could obviously influence the nitrate DRF for they are often internally mixed with each other.

Scalable, fluorine free and hot water repelling superhydrophobic and superoleophobic coating based on functionalized Al_(2)O_(3) nanoparticles

Journal of Materials Science & Technology 2021年第7期66卷 74-81页

作者： Binbin Zhang Weichen Xu Qingjun Zhu baorong Hou CAS Key Laboratory of Marine Environmental Corrosion and Bio-fouling Institute of OceanologyChinese Academy of SciencesQingdao 266071China Open Studio for Marine Corrosion and Protection Pilot National Laboratory for Marine Science and Technology(Qingdao)Qingdao 266237China Center for Ocean Mega-Science Chinese Academy of SciencesQingdao 266071China

Hot water droplet and oils induced air cushion failure, intensively used fluorine-containing chemicals,tedious preparation process, etc. are the main bottlenecks of the current artificially fabricated superhydrophobic materials, restricting their large-scale production and real-world applications. Herein, a facile,scalable, fluorine-free spray-coating strategy was employed to achieve superhydrophobic and superoleophobic polymerized organosilanes/Al2O3 nanoparticles(POS/Al_(2)O_(3) NPs) coatings. The POS/Al_(2)O_(3) NPs coating was achieved through hydrolytic condensation of tetraethyl orthoilicate(TEOS) and hexadecyltrimethoxysilane(HDTMS) in the presence of Al2O3 NPs. A variety of analytical techniques including scanning electron microscopy(SEM), X-ray photoelectron spectroscopy(XPS), energy dispersive X-ray photoelectron spectroscopy(EDS) were used to investigate the fabricated coatings. The POS/Al_(2)O_(3) NPs coating features high contact angle(>158°) and low sliding angle(<5°) for water, glycerol, and ethylene glycol droplets with different surface tensions, verifying both superhydrophobic and superoleophobic properties. Moreover, the coatings present extremely low surface adhesion force, excellent liquid-driven self-cleaning ability, and hot water repellency. The superamphiphobic POS/Al_(2)O_(3) NPs coating exhibits promising applications in various fields including self-cleaning, corrosion resistance, and preventing scald as this strategy is applicable on various substrates.

Effect of Sulfate-reducing Bacteria on Corrosion Behavior of Mild Steel in Sea Mud

引用

Journal of Materials Science & Technology 2007年第3期23卷 323-328页

Microbiologically influenced corrosion （MIC） is very severe corrosion for constructions buried under sea mud environment. Therefore it is of great importance to carry out the investigation of the corrosion behavior of marine steel in sea mud. In this paper, the effect of sulfate-reducing bacteria （SRB） on corrosion behavior of mild steel in sea mud was studied by weight loss, dual-compartment cell, electronic probe microanalysis （EPMA）, transmission electron microscopy （TEM） combined with energy dispersive X-ray analysis （EDX） and electrochemical impedance spectroscopy （EIS）. The results showed that corrosion rate and galvanic current were influenced by the metabolic activity of SRB. In the environment of sea mud containing SRB, the original corrosion products, ferric （oxyhydr） oxide, transformed to iron sulfide. With the excess of the dissolved H2S, the composition of the protective layer formed of FeS transformed to FeS2 or other non-stoichiometric polysulphide, which changed the state of the former layer and accelerated the corrosion process.
