Au interface. Needlelike AuSn4 IMCs were observed at the solder/0.5 μm Au interface.In Sn-2.0Ag-0.75Cu-3.0Bi and Sn-3.5Ag-O.75Cu solder joints, when the laser input energy was increased, AuSn4 IMCs......
Study on the Surface Free Energy of Ground CaO by JGC付正义摘 要:CaO formed by decomposing CaCO3 at 1450℃ was ground in a vibrational mill, then the long-time ground sample was reheated at different temperatures. Inverse Gas Chromatography (IGC) was used to measure the variation of the sample’s surface free energy under grinding and reheating......
and the results showed that ion irradiation could effectively reduce the surface roughness. In this work, a non-contact surface finish process was investigated with high-energy ion irradiation to improve... on the surface of the micro punch. The sputtering rate not only depends on the atomic mass and chemical bond of the material, but also relates to the energy, density and incident angle of the ions......
