摘要
高性能的表面微结构能够显著提升陶瓷制品的韧性和耐磨性能,提出一种基于激光加工的陶瓷表面微结构技术研究。首先分析激光加工的原理及工艺条件,对陶瓷制品表面的微结构进行有限元仿真;重点研究了激光入射功率、扫描速率及气流速度对陶瓷表面微结构烧蚀的影响。仿真数据表明经激光加工技术处理的陶瓷制品表面尺寸精度高、形貌良好,韧度和耐磨性能都有较大的改善。
High performance surface micro-structures can significantly improve the strength and wear resistance of ceramic products, therefore, a new technology for ceramic surface micro-structure based on laser processing is pro- posed. First analyzes the principle and process conditions of laser machining, makes finite element simulation of micro -structure of the surfaces of ceramic products. Focusing on the influences of laser power, scanning speed and flow speed on ceramic micro-structured surface ablation. The simulation data shows that the ceramic products processed by laser have high precision size, good appearance, and the strength and wear resistance have been greatly improved.
