精密陶瓷结构加工

2023年2月的材料领域权威期刊《Advanced Materials》报道了德国联邦材料研究与测试研究所（BAM）Sänger等人通过双光子聚合-烧结的技术路径制备了具有拓扑结构的陶瓷超材料。作者使用飞秒激光微纳加工综合系统-Laser Nanofactory中波长为780 nm的激光光源，制备出了最小线宽为500 nm的复杂拓扑钇稳氧化锆（YSZ）陶瓷超材料。研究结果表明：密度范围在1-4 g/cm⁻³的YSZ陶瓷超材料，其抗压强度就可达4.5 GPa。这一力学性能与传统块体YSZ陶瓷保持一致。该研究弥补了利用双光子聚合技术制备陶瓷材料的空白，借助Femtika的飞秒激光微纳加工综合系统-Laser Nanofactory将陶瓷超材料的制备精度提高到了亚微米尺度。
