Abstract

To explore the mechanism of material removal, this paper conducts a systematic study on picosecond laser processing of zirconia by using both theory and experiment. Comparing the multivariate lattice heat capacity of the Einstein and Debye models, two-temperature model (TTM) is developed to improve the accuracy of the temperature field. Then, to verify the effectiveness of TTM proposed, ablation experiments are performed by single-pulse picosecond laser on zirconia at different laser energy density. The results show that the measured craters profiles are well agree with the simulated melting/vaporization temperature distribution. Micro-morphology is significantly affected by phase transition induced by temperature rise. Moreover, the results confirmed that increased temperature can lead to transition in zirconia crystal structure and oxygen vacancies. Finally, the effect of coupling temperature variations on the elemental and physical phase variations are focused to investigate, which can help to optimize the processing quality due to crystalline phase transitions. This study provides guidance for optimizing picosecond laser processing of zirconia.

基于涉及多元晶格热容量的双温模型的氧化锆超短激光照射烧蚀特征

为了探索材料去除的机理，本文利用理论和实验对氧化锆的皮秒激光加工进行了系统研究。通过比较爱因斯坦模型和德拜模型的多元晶格热容，建立了双温模型（TTM），以提高温度场的精度。然后，为了验证 TTM 模型的有效性，使用单脉冲皮秒激光对氧化锆进行了不同能量密度的烧蚀实验。结果表明，测得的火山口轮廓与模拟的熔化/蒸发温度分布十分吻合。微观形态受温度升高引起的相变影响很大。此外，结果还证实，温度升高会导致氧化锆晶体结构和氧空位的转变。最后，重点研究了耦合温度变化对元素和物理相变的影响，这有助于优化因晶相转变而导致的加工质量。这项研究为优化氧化锆的皮秒激光加工提供了指导。
