厚度大于20 μm,沉积层的平均显微硬度为1803.2 HV,细小弥散分布的硬质相是沉积层硬度提高的主要因素. 关键词:WC-Co硬质合金;电火花沉积;组织结构;界面行为 中图分类号:TG174.445 文献标志码:A Interface behavior of WC-4Co coating by electro-spark deposition.... The behavior of interface between the coating and the substrate was studied by SEM and XRD. The surface wettability, the forming mechanism of phase, microstructure, element distribution of deposition, bonding......
; 文献标志码:A Surface-interface structures and characteristics of anodic oxidation film on 7475 aluminium alloy KONG De-jun, WANG Jin-chun, LIU Hao (College of Mechanical Engineering, Changzhou University, Changzhou 213016, China) Abstract: The layer of oxide film was prepared on the surface of 7475 aluminum alloy by anodic oxidation method. The surface-interface morphologies, chemical......
表明:β′相的键络强度较pre-β″和β″相的有所减弱,因此,β′相对合金的强化作用没有β″相的显著;β′相界面处的电荷密度连续性较弱,使得界面结合较弱,相界面处内应力较大,界面结合不够稳定.本研究将合金宏观性能的研究追溯到原子成键的电子结构层次.关键词:Al-Mg-Si合金;β′析出相;原子成键;界面Effect of atomic bonding of interface of β...:The atomic bonding, interface combined factor, crystal cohesive energy, interface energy between the precipitation with matrix were calculated using the empirical electronic theory in solid (EET......
Trans. Nonferrous Met. Soc. China 23(2013) 2454-2459 Effect of travelling magnetic field on interface morphology in directionally solidified Sn-Cd alloy Lei WANG, Jun SHEN, Ling-shui WANG, Zhou-rong...: The diversity of interface morphologies is observed for directionally solidified Sn-0.65%Cd alloy under a travelling magnetic field (TMF) in the 4 mm-diameter sample. Under an upward TMF, planar and cellular......
Trans. Nonferrous Met. Soc. China 22(2012) 1711-1716 Phase field calculation of interface mobility in a ternary alloy WANG Gang, ZENG De-chang, LIU Zhong-wu School of Materials Science... was proposed to calculate the interface mobility and applied to the α/β interface of a ternary Ti-6Al-4V alloy. Phase field simulations indicate that the higher interface mobility leads to the faster......
