Enhanced Sintering Performance of Ceramic Composites Fabricated by Powder Metallurgy

Abstract

In this study, we investigate the enhanced sintering performance of ceramic composites fabricated by powder metallurgy. The sintering process is a critical step in the production of ceramic composites, as it significantly affects the microstructure, mechanical properties, and overall performance of the final product. We employed a novel approach to optimize the sintering parameters, including temperature, pressure, and time, to achieve a uniform and dense microstructure with minimal porosity. The ceramic composites were fabricated using a mixture of alumina (Al2O3) and zirconia (ZrO2) powders, which were ball-milled to achieve a fine particle size distribution. The powders were then compacted and sintered under various conditions to study the effects of sintering parameters on the microstructure and mechanical properties of the composites. The results showed that the optimized sintering conditions led to a significant improvement in the density, hardness, and fracture toughness of the ceramic composites. The microstructure analysis revealed a uniform distribution of the ceramic phases and a reduction in the grain size, which contributed to the enhanced mechanical properties. The findings of this study provide valuable insights into the sintering process of ceramic composites and pave the way for the development of high-performance ceramic materials for various applications, including aerospace, automotive, and biomedical industries.
