Abstract Often ceramics employed for structural applications have to operate in harsh environments withstanding also solid particle erosion phenomena. Enhanced surface toughness and wear resistance of ceramic components can be achieved by laminated hybrid composites owing to the compressive residual stresses that can be generated into the surface by suitably combining the thermo-physical features of the different materials. In this work the superior solid particle erosion resistance of symmetrical Al2O3 and Al2O3–ZrO2 laminated composites compared to homologous Al2O3 bulk material has been experimentally assessed. Furthermore, based on the experimental results an heuristic solid particle erosion model able to correctly predict the erosion rate when testing conditions change has been proposed.

层状陶瓷结构的固体颗粒侵蚀行为

摘要 用于结构应用的陶瓷通常必须在恶劣的环境中运行，还要承受固体颗粒侵蚀现象。由于通过适当组合不同材料的热物理特性可以在表面产生压缩残余应力，因此层压混合复合材料可以提高陶瓷部件的表面韧性和耐磨性。在这项工作中，对称的 Al2O3 和 Al2O3-ZrO2 层压复合材料与同类 Al2O3 块状材料相比，其优异的固体颗粒侵蚀抗性已通过实验评估。此外，基于实验结果，提出了一种启发式固体颗粒侵蚀模型，能够在测试条件变化时正确预测侵蚀率。
