Electrochemical Properties of Al/Pb-WC-ZrO₂ Composite Coatings

Abstract:

Effects of the concentrations of solid particles in the bath and plating conditions on chemical components and polarization curves of oxygen separating out were studied by use of PARSTAT2263 electrochemistry testing instrument made by Research Center of Princeton and EPMA-1600 electron probe X-ray diffraction. And the results show that kinetic parameters of oxygen evolution of the obtained Al/Pb-WC-ZrO2 composite electrode materials are a=771mV, b=140mV, i0=3.11×10-6A·cm-2, and oxygen overvoltage is η=1009mV. The contents of WC and ZrO2 particles in the Al/Pb-WC-ZrO2 composite coating are 10.02wt% and 3.55wt% respectively when plating conditions are as follows: WC:50g/L,ZrO2:40g/L, bath temperature: 20°C, electric current density: 1.5A/dm2, plating time: 2h.
