摘要：

In the present paper, the porosity of the plating coating was evaluated by the combination of corrodkote and filter paper, the effects of the plating solution on the porosity were investigated, and the properties of the porous coatings were studied through scanning electron microscopy (SEM) and electrochemical potentiodynamic polarization. The results show that the eriothrome black T indicator used as an indicator of the coating porosity for coatings on magnesium alloy is more effective than magneson indicator and sodium alizarinesulfonate indicator. The porosity in electroless nickel deposits on magnesium alloy was well evaluated by the combination of corrodkote and filter paper. It is revealed that the pores exist on both grain surface and grain boundaries. An affecting trend of the plating bath parameters on the coating porosity was obtained. (c) 2005 Elsevier B.V.
