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 کاملSpectroscopic study of optical centers formed in Bi-, Pb-, Sb-, Sn-, Te-, and In-doped germanate glasses.
We have shown that the broadband near-IR (NIR) fluorescence recently discovered in Bi-doped glasses is not specific due solely to Bi ions. Glasses doped with different 6p (Bi, Pb) and 5p (Sn, Sb) ions exhibit very similar behavior characterized by four major spectral peaks observed in two-dimensional excitation-emission plots and the lifetime of metastable level of about 400 micros. Our results...
متن کاملSb-Bi Alloys and Ag-Cu-Pb-Sb-Bi Sulphosalts in the Jialong Cu-Sn Deposit in North Guangxi, South China
Although native bismuth is a relatively common mineral, native antimony is less abundant, and Sb-Bi alloys are relatively rare phases in Nature. Sb-Bi alloys and Ag-Cu-Pb-Sb-Bi sulphosalts have been discovered in the Jialong vein-type Cu-Sn deposit in North Guangxi, South China. The Jialong deposit is hosted by schist within the contact zone of a Neoproterozoic granite. Four stages of ore forma...
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 کاملA Comparative Kinetic Study of Pb and Pb-Sb Electrodes in Sulfuric Acid Solutions
As respostas eletroquímicas de eletrodos de Pb e de Pbs-3.4%Sb em H2SO4 5 M foram examinadas combinando as técnicas de varredura e saltos de potencial. A presença do antimônio evita o bloqueio completo da superfície ativa do eletrodo por cristais de PbSO4 du rante a eletrooxidação, mudando a composição e a estrutura da camada passiva. A eletrooxidação do Sb tem sido interpretada em termos de um...
