摘要: Ni-P, Ni-P-TiO2 and Ni-P-SiC composite coatings on AZ91D magnesium matrix were prepared by the electroless depositing. The surface morphology of was observed scanning electronic microscopy(SEM) electron probe X-ray microanalyser(EPMA). corrosion resistance studied electrochemical method impact TiO 2 SiC analyzed. results showed that nano-TiO2 nano-SiC particles refining depositing, cause depositing loose, reduced. potential is over -0.8V when 2g/L TiO2 or added in solution, though potentials lower than Ni-P coating(lower -0.5V), it still shows a protective effect for composite.
