摘要：

The microstructure and corrosion behavior of Al-5 wt.% TiB2/TiC composites after hot rolling treatment were investigated by scanning electron microscope, immersion tests, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) in 3.5 wt.% NaCl solution. The results show that corrosion of alpha-Al phase initiates at the interfaces between the matrix and the agglomeration clusters of TiB2 and TiC particles. After hot rolling deformation, the dispersive distribution of reinforcement particles and the grain refinement of the Al matrix suppressed the rapid expansion of corrosion pits, which become smaller and shallower, indicating that the corrosion resistance of Al-TiB2/TiC composites has been enhanced by hot rolling treatment.
