编辑推荐： 本研究针对SiCp /Al复合材料超声焊接中晶粒粗化导致接头强度不足的问题，创新性地引入脉冲电流（Pulsed current）技术。 研究人员通过调控位错运动与电子密度分布，将铝基体晶粒尺寸从15 μm细化至2 μm，接头抗拉载荷提升85%（3.7 kN vs 2.0 kN）。

The pulsed charging also suppresses the structural changes of NMC532 cathode materials with less Ni-O bond length variation. The pulse current frequency is crucial ...

Electroplating refers to the process of plating one metal onto another by hydrolysis and is most commonly used to prevent the corrosion of metal or for decorative purposes. The pulse current ...

Pulse widths are adjustable from 25 microseconds to 8,750 microseconds (maximum pulse width varies by model), with a pulse repetition frequency up to 20 hertz. Output current is set with an ...
