X-Ray Photoelectron Spectroscopy Study of Passive Layers Formed on Pb-Sn and Pb-Sb Alloys
In this article, passivated Pb-Sn and Pb-Sb alloys with different compositions were studied by X-ray photoelectron spectroscopy (XPS). The passive films were found to have a double-layer structure. Both Sn and Sb were found to play an important role during the growth of passive film, which resulted in different compositions of passive filJ;l1s. The Pb oxides, Pb sulfate, SnlSb oxides, and Pb-Sn...
متن کاملThe Mechanical Strength of Si Foams in the Mushy Zone during Solidification of Al–Si Alloys
The mechanical strength of an Al-30% Si alloy in the mushy zone was estimated by using a novel centrifugation apparatus. In the apparatus, the alloy melt was partially solidified, forming a porous structure made of primary Si platelets (Si foam) while cooling. Subsequently, pressure generated by centrifugal force pushed the liquid phase out of the foam. The estimated mechanical strength of the ...
متن کاملEffects of Buoyancy Parameter on Unsteady 3d Double Diffusive Convection in Molten Pb-sn Alloys
A computational study has been made for a three dimensional double diffusive convection with molten Pb-Sn by using finite volume method. In this work, two vertical walls have different temperature and different concentration while remaining walls are adiabatic. Buoyancy ratio, which changes between N = -0.1 and -10, is the main governing parameter during work. Other parameters are taken as fixe...
متن کاملThe Kinetics of Formation of Ternary Intermetallic Alloys in Pb-Sn and Cu-Ag-Sn Pb-free Electronic Joints
A simple model of the formation of Au0.1Ni0.1Sn0.8 in Pb-Sn solder/Ni interconnects is examined by numerical simulation. Previous experimental observation has shown that after reflow the interface consists of the Ni3Sn4 alloy between Pb-Sn solder and Ni, with Au distributed through the PbSn solder ball. Au0.1Ni0.1Sn0.8 was observed to form at the Pb-Sn solder/Ni3Sn4 interface during annealing a...
متن کاملMeasuring intrinsic elastic modulus of Pb/Sn solder alloys
Young’s modulus (E) values published in the literature for the eutectic Pb37/Sn63 and near eutectic Pb40/Sn60 solder alloy vary significantly. One reason for this discrepancy is different testing methods for highly rate sensitive heterogeneous materials, like Pb/Sn alloys, yield different results. In this paper, we study different procedures used to obtain the elastic modulus; analytically, by ...
