ABSTRACT

The latest technological requirement demands a huge (but sometimes challenging) variety of properties which perhaps are impossible in monolithic or traditional materials. This has innovated the introduction of reinforcement in traditional materials such that the resulting composite material would be an advantage for the collaborating influence of the combined matrix and the reinforcement. Single-phase ceramics have been limited in application due to low densification and poor properties. Hence, ceramic matrix composite is the family of materials that have undertaken quick innovation in past years because of its auspicious properties for structural and functional usage. This concept has made the incorporation of sintering additives into the monolithic form of ZrO₂ of high importance because of the poor densification and fracture toughness of undoped ZrO₂. The addition of sintering additives provides good functionality to the improvement of ceramic materials. This paper painstakingly reviews the effects of diverse sintering additives such as carbides, borides, nitrides on the microstructure, densification, and mechanical properties of ZrO₂ ceramic matrix using different sintering techniques and it lastly stated a futuristic approach to the enhancement and characterisation needed for ZrO₂ ceramic matrix composites.

摘要

最新的技术要求需要大量（但有时具有挑战性）的特性，这在整体或传统材料中可能是不可能的。这对在传统材料中引入增强材料进行了创新，因此所得复合材料将成为组合基体和增强材料协同影响的优势。单相陶瓷由于致密度低和性能差而限制了其应用。因此，陶瓷基复合材料是过去几年快速创新的材料家族，因为它具有良好的结构和功能用途。这个概念使烧结添加剂加入到 ZrO ₂的整体形式中由于未掺杂的 ZrO _{2 的}致密性和断裂韧性较差，因此具有很高的重要性。烧结助剂的加入为陶瓷材料的改进提供了良好的功能。本文精心回顾了碳化物、硼化物、氮化物等各种烧结添加剂对使用不同烧结技术的 ZrO ₂陶瓷基体的微观结构、致密化和机械性能的影响，最后提出了一种用于增强和表征 ZrO 所需的未来方法₂陶瓷基复合材料。
