  Interface structure of TaN/ReB2 multilayers was investigated using first-principles based on density functional theory (DFT). Twelve different interface configurations of TaN(100)/ReB2(001) were chosen to calculate the interface energy, taking into account both N- and Ta-terminations. The interfacial electronic properties including charge density distribution, states of density (DOS) and mulliken population were simulated to determine the nature of interface bonding. The results showed that B-N interface had the strongest bonding combined covalent bonding. The B-N interfaces and B-N-top configuration were the most stable interface and configuration. Meanwhile, atomic population and n mber of electrons of interface were calculated to predict the mechanical properties of monolithic TaN and ReB2 coatings and TaN/ReB2 multilayers.

随着人民生活水平的提高,消费者在选购产品的时候,不再只关注产品功效,同时也注重产品使用时的精神享受,如舒适的触感等。皮肤接触和感知产品表面的过程即为摩擦的过程,所产生的摩擦力,即接触摩擦力,能够激发皮肤内的四种响应机械刺激的感觉神经元,从而获得不同的触感。而表面织构作为一种可以显著改善表面摩擦学性能的方法受到了国内外科学技术工作者的广泛关注。因此,通过对与皮肤接触的产品表面进行织构,能够影响其与皮
Tactile perception of surfaces is an essential aspect of our daily life and has a profound importance for our well-being. The tactility (rough/smooth, slippery/sticky, comfort, etc.) is perceived by t

NiCrAlY coatings of 200 m thick were deposited on Ni-base superalloy (Ni-51.21%, Cr-19.7%, Al-0.37%, Nb-5.39%, Mo-3.18%, Ti-1.34%, Fe-18.81%) by electron-spark deposition to enhance the oxidation resi
采用射频磁控溅射技术,在Si(100)基底上制备相同厚度不同调制周期的HfN/HfB2纳米多层膜来获得不同的调制周期对其结构和机械性能的影响.利用XRD、TEM、Xp-2台阶仪、纳米压痕仪及摩擦试验机分别分析了多层膜的结构特征、机械性能和室温下摩擦性能.结果 表明:室温下沉积的多层膜表现出结晶/非晶的混合结构;随着调制周期的增大,多层膜的硬度和弹性模量呈现出先增大后减小的趋势,当调制周期为40 n
铝铜异种金属接头广泛应用于电力、化工、制冷和航空航天工业等邻域中,焊接是实现铝铜连接并满足其接头导电、导热性能的可靠方法,但仍然存在一些问题。首先,铝和铜焊接性较差,两种金属都很容易被氧化,易在界面形成氧化膜,影响结合;其次,两者的导热率和比热都较高,线膨胀系数及熔点相差较大,直接连接将产生很大的焊接应力;此外,在高温下,两种金属液体易吸收大量气体,使得焊缝中出现气孔,同时易形成Cu3Al2和Cu

在铝合金表面通过阳极氧化法在多孔层外构筑一层光滑致密的耐磨层是一项有挑战的工作.本文中阴极和阳极均采用铝合金,通过调控草酸和铝离子浓度,在铝合金表面构筑了新颖的多层结构,除传统阳极氧化膜的阻挡层和多孔亚表层以外,表面构筑了一层光滑致密的耐磨表层.通过扫描电镜、XRD、XPS、EDS分析了这种新型阳极氧化膜的表面形貌和化学组成.结果 表明耐磨表层由非晶态氧化铝组成,其表面光滑致密有别于传统阳极氧化膜
表面超疏水特性是自然界中极为常见的现象,通常将超疏水表面定义为与液滴接触角大于150°,滚动角小于10°的表面。人们在认识与研究自然过程中,试图将仿生属性与某些特性相结合,透明超疏水表面便是其中应运而生的代表产物。顾名思义,透明超疏水表面是将材料的透光性与超疏水性相结合的表面,这类表面具有广泛的应用前景,例如它可被应用于汽车挡风玻璃、室外窗户玻璃、眼镜镜片以及手机屏幕等。材料的透光性与表面疏水性能
