Abstract:

A series of Al/Ni composites were fabrication with friction stir processing to investigate the effect of PTFE on the homogeneity of Ni distribution in the composites. The microstructures of the surface composites were analyzed by SEM and EDS, the phase composition was examined by XRD. Results show that the uniformity of composites can significantly improved by adding PTFE; the interface between Ni and Al will be increase after adding PTFE, because the PTFE can Blocking Ni powder together. Then , the reaction degree between Al and Ni will be increase, so the number of Al₃Ni intermetallic compound will be increase.
