Bonding mechanism of ultrasonic wedge bonding of copper wire on Au/Ni/Cu substrate TIAN Yan-hong(田艳红)1, WANG Chun-qing(王春青)1, Y. Norman ZHOU2 1. State Key Laboratory of Advanced Welding...; Abstract: The ultrasonic wedge bonding with d25 μm copper wire was achieved on Au/Ni plated Cu substrate at ambient temperature. Ultrasonic wedge bonding mechanism was investigated......
. Diffusion bonding tests were carried out on the Gleeble-1500 testing machine and the specimens were successfully diffusion bonded at the superplastic temperature. The maximum specific strength is 0.82... with high specific strength. Key words: ZK60 magnesium alloy; lap bonding; superplasticity; specific strength CLC number: TG146.22 ......
of sputtering power on the microstructure and the bonding strength between the film and substrate were investigated. AFM observation proves that the dense films are obtained, and the surface roughness... an intense relationship between the power and crystal structures. The scratch test shows that interface bonding strength of the film/substrate is higher at the power of 44 W than the others, due......
,导致铝受到镀液的腐蚀,是造成一次浸锌处理后铝/电镀镍结合强度较差的主要原因. 关键词:浸锌层；铝；电镀镍；结合强度 中图分类号:TQ153.4 文献标志码:A Effect of zinc coating process on bonding strength of aluminium/electroplated nickel LUO Yang1... of zinc coating process on the surface morphology of aluminium and the bonding strength of aluminium/electroplated nickel, aluminium was coated with single and secondary zinc layer before electroplating......
relationships were developed to predict diffusion layer thickness, hardness and strength using response surface methodology. It is found that bonding temperature has predominant effect on bond characteristics. Joints fabricated at a bonding temperature of 450 ℃, bonding pressure of 12 MPa and bonding time of 30 min exhibited maximum shear strength and bonding strength of 66 and 81 MPa, respectively. Key......
between coating and micro-porous layer were analyzed by SEM, XRD and line scanner. The effect of micro-porous structure on bonding strength of the coating was studied. The results show..., although there is no element diffusion between the interface. Compared with the direct laser cladding Al2O3-13%TiO2 coating on the surface of Ni625 alloy, the bonding strength of the 316L micro......
