摘要
The effects of hydrolysis of the AlN particulates on corrosion behavior of Al/AlNp composite were examined by analyzing potentio-static anodic current transient, cyclic voltammetry curves and potentiodynamic cathodic polarization curves. It is found that the degree of hydrolysis of AlN particulates in the composite increase with the pre-hot water treatment time, which increase the occurrence of metastable pits in the composite. In addition, hydrolysis of AlN particulates also affects the electrochemical corrosion behaviors of the composite, and makes Al/AlNp composite show intergranular corrosion behavior to some extent.
