Effect of Fiber Coating on Properties of Ni-MF/Al₂O₃ Composites

Abstract:

By adding sintering additives (CMS and nanoTiO₂), Ni-MF/Al₂O₃ composites were prepared by pressureless sintering. In order to ameliorate the combination between mullite fiber and alumina matrix, mullite fiber surface was coated with Al₂O₃ coating. To improve the property of alumina ceramic composite, Ni particles were chosen as toughening phase. For the preparation of composite, the optimum process was 10% MF, 13% Ni, and sintering temperature in 1400°C. The material performance can be effectively improved.
