Spark Plasma Sintered Joining between Lead Zirconate Titanate and Aluminum with Sn-3.5Ag Alloy Powder as an Insert Material

Abstract

Study on joining between piezoelectric ceramics and aluminum was performed by Spark Plasma Sintered (SPS) joining method. An insert material for a joining between lead zirconate titanate (PZT) and aluminum used the Sn-3.5Ag alloy powder. The joining samples are produced by SPS at 473K for 300s to 7.2ks. The shearing test was carried out to investigate the mechanical property of the joining samples. The maximum shearing stress of 25MPa was able to be obtained. Any joining samples are ruptured at Sn-3.5Ag/Aluminum interface. The sintering time increased with increasing shearing stress and decreasing insert materials thickness and electric resistivity.
