Abstract

We have conducted joining between AlN ceramics by spark plasma sintering (SPS) process and examined the effects of TiH₂ coating on AlN and the insertion of Ti and Cu foils. Titanium hydride was decomposed and a joint was formed by heating at 500°C for 10 min. The resultant reaction layer has a shear strength of 24.8 MPa. The interface layer was characterized using scanning electron microscope (SEM), electron-probe microanalyzer (EPMA) and x-ray diffraction (XRD).
