Preparation of Mg-Cu Composite by Tape Casting and Hot-Pressing

Abstract:

The preparation of 50Mg/50Cu composite by tape casting and hot-press sintering was studied. During the preparation of the slurry and tapes, the effects of different organic additives were discussed and the contents of the organic additives were optimized. Then the sintering temperature of the green samples were discussed to get densified 50Mg-50Cu samples. The slurry was characterized by viscosity. And the tapes and the final 50Mg-50Cu sample were anaylsed by density, XRD and SEM. The viscosity results indicated that the slurry with well-dispersed and stable properties for tape casting could be obtained. The solid loading of the slurry is 48wt%. After tape casting, the density and uniform tapes were made. The XRD and SEM results demonstrated that the optimal sintering temperatures of Mg-Cu composite were from 460°C to 470°C.
