| 1 | 6061铝基体上镍涂层热处理过程中Ni-Al金属间化合物的形成机理(英文)显示文摘采用电沉积方法在Al基体上沉积Ni制备Ni-Al扩散偶,并研究扩散偶中Al3Ni和Al3Ni2的形成机理和生长动力学。在6061铝基体上采用直流电沉积方法制备20μm厚的Ni涂层。然后在Ar气气氛下,样品在450,500和550°C下热处理不同时间。采用扫描电子显微镜、能谱仪和X射线衍射仪对金属间化合物进行表征。结果表明,Ni-Al金属间化合物的形成可分为两个重要步骤。首先,金属间化合物在不同位置侧面生长,形成连续金属间化合物层;其次,连续金属间化合物层在垂直于界面方向继续生长。随着金属间化合物厚度的增长,Al3Ni和Al3Ni2等反应产物将与基体发生分离。Al是Al3Ni生长的主要扩散元素,而Ni是Al3Ni2生长的主要扩散元素。Al3Ni和Al3Ni2相的生长动力学遵循抛物线方程。 | Mohsen ADABI Ahmad Ali AMADEH | 2015 | Transactions of Nonferrous Metals Society of China2015，25，12： | 7 |
| 2 | Effect of Electroplating Parameters on Microstructure of Nanocrystalline Nickel Coatings显示文摘In order to achieve the optimum conditions for electroplating nanocrystalline nickel coating from Watts-type bath, the effect of some process parameters namely, bath temperature, current density, and saccharin addition on grain size and texture coefficient (TC= I(200)/I(111)) of the deposits were investigated by X-ray diffraction (XRD). The results showed that in a bath containing 5 g/L saccharin, by increasing the bath temperature from 45°C to 55°C, the grain size decreased, whereas further increase of bath temperature resulted in a contrary effect. By increasing the current density from 10 to 75 mA/cm2, both the grain size and TC decreased, while further increase in current density had no significant effect on the grain size. At a given current density, the grain size and TC decreased rapidly by increasing the saccharin content before leveling off at 3 g/L of saccharin. Finally, based on the grain refining the optimum conditions for producing nanocrystalline nickel coating from Watts-type bath have been proposed. | A.M. Rashidi A.

| 3 | 镍-铝复合涂层的电沉积机理(英文)显示文摘在改进的Watts溶液中电沉积镍-铝复合涂层。采用Z电位分析、伏安法和电化学阻抗谱(EIS),研究涂层的电化学行为。结果发现,铝颗粒的Z电位是-4 mV,与氧化铝的非常接近。添加导电铝颗粒到电解液中,导致极化曲线向负电位方向移动,且EIS曲线的环路尺寸增大。结果表明,镍-铝复合层的共沉积行为服从Guglielmi模型。加入的导电铝颗粒起惰性粒子的作用,证实在铝颗粒表面存在薄的氧化铝层。 | Mohsen ADABI Ahmad Ali AMADEH | 2014 | Transactions of Nonferrous Metals Society of China2014，24，10： | 2 |
| 4 | Microstructure and wear behavior of AA6061/SiC surface composite fabricated via friction stir processing with different pins and passes显示文摘In this investigation,the effects of pin geometry and number of passes on macrostructure,microstructure,wear rate and also microhardness profile of 6061-T6 aluminum alloy surface composites fabricated via friction stir processing(FSP)were discussed by reinforcement particles of silicon carbide(SiC).The results show that after each FSP pass,a modify distribution of SiC particles is acquired and the increase in the number of passes reduces the average grain size in stir zone(SZ).Furthermore,it is discovered that pin geometry and pass number play a dominant role in the grain size of SZ and distribution of SiC particles in SZ.It is found that after each FSP pass,wear rate is improved due to the uniform distribution of SiC particles in surface of Al/SiC composite.Additionally,the results show that the square pin and smooth(straight)cylindrical pin have the highest and lowest resistance to wear,respectively. | Hamidreza Eftekharinia Ahmad Ali Amadeh Alireza Khodabandeh Moslem Paidar | 2020 | Rare Metals2020，39，4： | 2 |
| 5 | 用铜锌中间层瞬时液相连接Al 2024和Ti-6Al-4V合金(英文)显示文摘采用Cu-22%Zn中间层,在510℃、真空度为0.01 Pa和不同连接时间下将两种异质合金Al 2024和Ti-6Al-4V进行瞬时液相连接。采用SEM、EDS和XRD技术对连接区的显微组织演变进行表征。结果表明,接头的形成归因于Cu和Zn固相扩散进入Ti-6Al-4V和Al2024合金中,然后形成共晶并沿Cu-Zn/Al 2024界面等温扩散。接头界面处的硬度随连接时间的延长而增加,这是由于形成了Al_2Cu、TiCu3、Al_(4.2)Cu_(3.2)Zn(0.7)、Al_(0.71)Zn_(0.29)、Ti_2Cu、TiAl_3和TiZn_(16)金属间合物。此外,当连接时间为60 min时,接头的剪切强度达到最大,为37 MPa。 | Majid SAMAVATIAN Ayoub HALVAEE Ahmad Ali AMADEH Alireza KHODABANDEH | 2015 | Transactions of Nonferrous Metals Society of China2015，25，3： | 2 |
