原始语种摘要: Abstract(#br)In this paper, an Al/TiB 2 layered composite was prepared by plasma spraying for use as the base material to reduce resistivity and improve electrochemical performance in an electrode. The β-PbO 2 coating was prepared by electrochemical deposition. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to study the Al/TiB 2 composite and the β-PbO 2 coating. The electrochemical performance of the Al/TiB 2 /β-PbO 2 and Ti/β-PbO 2 composites was studied by linear sweep voltammetry (LSV), Tafel polarization curves (Tafel) and electrochemical impedance spectroscopy (EIS). The results indicate that Al/TiB 2 /β-PbO 2 composite electrode materials with a uniform structure were successfully prepared by plasma spraying and electrochemical deposition. The structure of...
