Composite Chemical Copper Plating of Ultrafine SnO2 Powder

The reaction conditions of composite chemical copper plating of ultrafine solid SnO 2 particles were studied. The influences of bath temperature, pH value and concentration of SnO 2 on anti wear property and plating rate were discussed. The result show that an optimum composite Cu SnO 2 plating layer can be got when bath temperature is 70°C, pH value is 12.5, and concentration of SnO 2 is 9 g/L. The anti wear and anti oxidation properties of the composite plating were improved. XRD analysis shows that SnO 2 has been incroporated into the composite plating layer.
