| 1 | CNTs和Nb纳米颗粒提高电力传输线用放电等离子体烧结铝合金的摩擦和热性能(英文)显示文摘用放电等离子体烧结法(SPS)制备铝合金,以碳纳米管(CNTs)和Nb纳米颗粒作为增强相,提高合金的摩擦性能和热性能。SPS工艺参数为:630℃、30 MPa、10 min和200℃/min。而且,以钢球为对磨件,采用球-盘式摩擦试验机对样品进行摩擦学试验。用热重分析仪(TGA)和激光导热仪(LFA)进行热性能分析。结果表明,分别添加8 wt.%的CNTs和Nb纳米颗粒使复合材料的摩擦因数(COF)降低79%。磨损量和磨损率也降低23%,且复合材料的热导率提高44%。摩擦性能的改善是由于CNTs的加入导致材料表面形成C薄膜,以及由于Nb纳米粉末的加入而生成起保护作用的Nb2O5。导热性能的改善是由于Nb的晶粒细化作用和CNTs的高导热性。因此,这些结果表明,Al-CNTs-Nb复合材料是高压输电导线用的坚固材料,能够减小下垂并保证材料的使用寿命。 | Chika O.UJAH Patricia POPOOLA Olawale POPOOLA Victor AIGBODION Philip OLADIJO | 2020 | Transactions of Nonferrous Metals Society of China2020，30，2： | 1 |

| 4 | Corrosion Resistance ofAA6063-Type AI-Mg-Si Alloy by Silicon Carbide in Sodium Chloride Solution for Marine Application显示文摘The present work focused on corrosion inhibition of AA6063 type Al-Mg-Si alloy in sodium chloride(Na Cl) solution with a silicon carbide inhibitor, using the potentiodynamic electrochemical method. The aluminium alloy surface morphology was examined, in the as-received and as-corroded in the un-inhibited state, with scanning electron microscopy equipped with energy dispersive spectroscopy(SEM-EDS). The results obtained via linear polarization indicated a high corrosion potential for the unprotected as-received alloy. Equally, inhibition efficiency as high as 98.82% at 10.0 g/v silicon carbide addition was obtained with increased polarization resistance(Rp), while the current density reduced significantly for inhibited samples compared to the un-inhibited aluminium alloy. The adsorption mechanism of the inhibitor aluminium alloy follows the Langmuir adsorption isotherm. This shows that the corrosion rate of aluminium alloy with silicon carbide in Na Cl environment decreased significantly with addition of the inhibitor. | Ojo Sunday Isaac Fayomi Malik Abdulwahab Abimbola Patricia ldowu Popoola Ferdinand Asuke | 2015 | Journal of Marine Science and Application2015，14，4： | 0 |

| 7 | Anti-Corrosion and Tribo-Mechanical Properties of Co-deposited Zn–SnO_2 Composite Coating显示文摘Zn–Sn O2 composite coatings were prepared by direct potential using electrolytic co-deposition technique from sulfate solution.The effect of Zn2?and Sn O2 concentrations in deposited bath on the mechanical properties and morphological characteristics of the composite coatings were examined.The characterizations of the sample were analyzed using scanning electron microscopy couple with energy dispersive spectroscopy(SEM/EDS),X-ray diffraction(XRD) and atomic force microscopy(AFM).The electrochemical degradation behavior of the samples in 3.65 wt.% Na Cl solution was studied using potentiodynamic polarization technique and characterized by high-resolution optical microscope.From all the fabricated composite coatings,obvious diffraction peaks were observed with Zn-7Sn-S-0.3V film with Zn2Sn7,Sn,Zn2Sn5 and Zn phases,confirming the presence and formation of Zn–Sn O2 coating.The XRD pattern shows that the presences of Sn O2 particle remarkably play a major role in the precipitation and orientation of the alloy matrix.From the SEM/EDS and AFM results,the deposits show that composite particle and proper bath composition have strong influence on the microstructure.An enhanced corrosion resistance was attained as a result of the induced particles. | Ojo Sunday Isaac Fayomi Abimbola Patricia Idowu Popoola | 2015 | Acta Metallurgica Sinica(English Letters)2015，28，4： | 0 |
