| 1 | Investigation of the Ce-Mn conversion coating on 6063 aluminium alloy显示文摘In this paper,the sustainable Ce-Mn chemical conversion coating was fabricated on 6063 aluminium alloy by means of Ce(NO3)3 and KMnO4 as the inhibitors and NaF as the accelerator.The morphologies,composition and valence state of the coating were analyzed by scanning electron microscopy(SEM),energy dispersive spectrometry(EDS) and X-ray photoelectron spectroscopy(XPS),respectively.The results indicated that the Ce-Mn conversion coating was formed.The anticorrosion of the coating was evaluated in 3.5 wt.% NaCl aqueous solution at room temperature by using polarization curve and electrochemical impedance spectroscopy(EIS).It indicated that the treated surface presented better anticorrosion behavior in chloride media than on the original material surface.The corrosion resistance of Ce-Mn conversion coating was about equal to the trivalent chromium conversion coating. | ZHANG JunJun LI WenFang DU Jun HAN Dong ZHENG XiaoPing | 2010 | Chinese Science Bulletin2010，55，29： | 9 |

| 6 | Tetrahydro-dibenzo[a,d]Annulene-5,11-Dihydrazone and Magnesium Oxide Used to Control the Corrosion of Aluminium in Chloride Ions Environment显示文摘Chloride ions interact with aluminium in marine atmosphere to form corrosion cell.Due to this corrosion reaction occurs on their surface,aluminium is oxidized into Al3+.The corrosion reaction accelerates deterioration in metal and it produces galvanic,pitting,stress,crevice,intergranular corrosion.Chloride ions decrease internal and external strength of aluminium metal.It is a very important metal so used in different appliances for e.g.road,water,air transports,housing,railways and other fields.Nanocoating and electrospray techniques used to check the corrosion of aluminium metal.For nanocoating and electrospray materials applied tetrahydro-dibenzo[a,d][7]annulene-5,11-dihydrazone and MgO.Both materials formed composite barrier and developed a passive surface for Cl-ions.This barrier reduced the corrosion rate of aluminium.Nozzle spray and chemical vapour deposition technique used for coating process.The corrosion rate of metal was determined by gravimetric method.Corrosion potential and current density were calculated by potentiostat.The composite barrier formation was confirmed by activation energy,heat of adsorption,free energy,enthalpy and entropy.These thermal parameters were obtained by Arrhenius equation,Langmuir isotherm and Transition state equation.The adsorption of tetrahydro-dibenzo[a,d][7]annulene-5,11-dihydrazone and MgO electrospray on aluminium surface was depicted by Langmuir,Frundlich and Temkin isotherm.The results of surface coverage area and coating efficiency were noticed that both materials were mitigated the corrosion rate of aluminium in chloride ions environment. | Rajesh Kumar Singh Jay Prakash Singh Dharmendar Kumar | 2020 | Journal of Metallic Material Research2020，3，2： | 0 |
| 7 | Insight into the covalent grafting of organic films onto carbon steel surfaces for protection显示文摘The novel use of p-nitrophenyldiazonium tetrafluoroborate salt(GG salt)as a protectant that is electrochemically grafted onto carbon steel has been investigated in0.05 mol L-1H2SO4and 5 wt%NaCl solutions using various corrosion monitoring techniques,such as electrochemical impedance spectroscopy,potentiodynamic polarisation,infrared spectra and scanning electron microscopy measurements.The electrochemical study reveals that this compound is a mixed inhibitor that predominantly controls the cathodic reaction.The surface-grafted film decreases the double-layer capacitance and obviously increases the charge transfer resistance relative to a bare carbon electrode.The values of inhibition effect remain nearly unchanged with an increase in temperature range of 298–318 K.The aryl diazonium is covalently bonded on the steel surface,causing a slight decrease in the apparent activation energy.Overall,the surface-grafted films exhibit excellent inhibition performance in acid and saline solutions within the studied temperature range. | Sheng-Juan Huo Li-Hong Chen Chen-Sheng Chu Jian-Hui Fang | 2014 | Chinese Science Bulletin2014，59，10： | 0 |
