Abstract

The relentless effort for the innovation of improved materials for application in high-temperature environment, structural and functional application has paved the way for the synthesis of ceramics based materials—with current research activities being channeled towards the application of metallic and non-metallic based nano-powders as a sintering additive or as a reinforcement for ceramic-based materials. Metallic and non-metallic based nanopowders additive possesses excellent thermal, physical, and mechanical properties and hence, serves as a good additive for ceramic-based materials in achieving good sinterability, full densification, and excellent mechanical properties. One of the critical factors that have affected the densification and properties of the ceramic-based material is the type of consolidation applied. Powder metallurgy (PM) is the most prominent technique to date for the syntheses of ceramic-based materials. Although previous reviews have stated diverse PM techniques viz., hot press, hot-isostatic press, pressureless sintering, spark plasma sintering (SPS). More also, various reinforcement such as Metallic and non-metallic based nano-powders additive has been used in achieving the desired properties. SPS amidst diverse PM techniques has been given high attention to the routes of manufacturing ceramic materials because good microstructures and excellent mechanical properties can be achieved. This review focuses on past, present, and future works of ZrB₂, and TiB₂, reinforced with sintering additive with more attention on silicides, carbides, or nitrides based material as sintering additive.

ZrB 2和TiB 2陶瓷基复合材料的火花等离子体烧结：微观结构，致密化和力学性能—综述。

摘要

为改进用于高温环境，结构和功能应用的改良材料而进行的不懈努力，为合成陶瓷基材料铺平了道路，而目前的研究活动则转向金属基和非金属基纳米材料的应用-粉末作为烧结添加剂或作为陶瓷基材料的增强材料。金属和非金属基纳米粉体添加剂具有优异的热，物理和机械性能，因此，在获得良好的烧结性，完全致密化和出色的机械性能方面，可作为陶瓷基材料的良好添加剂。影响陶瓷基材料致密化和性能的关键因素之一是所施加的固结类型。粉末冶金（PM）是迄今为止合成陶瓷基材料的最杰出技术。尽管先前的评论已经指出了多种PM技术，例如热压，热等静压，无压烧结，火花等离子烧结（SPS）。此外，为了获得期望的性能，已经使用了各种增强材料，例如基于金属和非金属的纳米粉末添加剂。由于可以实现良好的微观结构和优异的机械性能，因此在多种PM技术中的SPS已引起人们对陶瓷材料制造路线的高度关注。这篇评论集中在ZrB的过去，现在和将来的作品上 无压烧结，火花等离子烧结（SPS）。此外，为了获得期望的性能，已经使用了各种增强材料，例如基于金属和非金属的纳米粉末添加剂。由于可以实现良好的微观结构和优异的机械性能，因此在多种PM技术中的SPS已引起人们对陶瓷材料制造路线的高度关注。这篇评论集中在ZrB的过去，现在和将来的作品上 无压烧结，火花等离子烧结（SPS）。此外，为了获得期望的性能，已经使用了各种增强材料，例如基于金属和非金属的纳米粉末添加剂。由于可以实现良好的微观结构和优异的机械性能，因此在多种PM技术中的SPS已引起人们对陶瓷材料制造路线的高度关注。这篇评论集中在ZrB的过去，现在和将来的作品上₂和TiB ₂，用烧结添加剂增强，更重视硅化物，碳化物或氮化物基材料作为烧结添加剂。
