| Abstract: | The corrosin resistance of SiCp/Al composites with different amount of Mg was investigated by the salt-fog test and alternate immersion test.Mass loss was used to evaluate the corrosion rate.The phase constituent and surface morphology of corrosion products were characterized by X-ray diffraction(XRD) and scanning electron microscope(SEM).Experiment results showed that,with the addition of Mg,a flat plateau appeared on the polarization curves indicating passivation of the composites with Mg.While oxide scal... |
