Abstract

The investigations applied the original concept of the formation of materials as hybrid gradient composites. Two innovative technologies were used: formation by centrifugal slip casting and sintering with varying proportions of the liquid phase. This allowed us to create a gradient microstructure. This article presents the study of Al₂O₃-Cu-Mo gradient composites. This work aimed to determine the effect of the metallic phase content on the composite’s microstructure and basic properties. The most critical element of the study will be determining the ability to control the location and flow of the liquid phase during the sintering process. The research demonstrated that adding a third component in the form of Mo reduces the liquid Cu flow onto the surface of the composites during the sintering process. In this research, we achieve results with high cognitive value.

通过离心滑移铸造获得新型功能梯度复合材料 Al2O3-Cu-Mo

摘要

研究应用了将材料形成为混合梯度复合材料的原始概念。使用了两种创新技术：离心粉浆浇铸成型和不同比例的液相烧结。这使我们能够创建梯度微观结构。本文介绍了 Al ₂ O ₃的研究-Cu-Mo 梯度复合材料。这项工作旨在确定金属相含量对复合材料微观结构和基本性能的影响。该研究的最关键要素是确定在烧结过程中控制液相位置和流动的能力。研究表明，添加 Mo 形式的第三种组分会减少烧结过程中液态 Cu 流到复合材料的表面。在这项研究中，我们取得了具有高认知价值的结果。
