高硬脆陶瓷激光加工技术的研究及进展

Researches and developments of Laser processing ceramics technique

随着陶瓷材料应用领域的不断扩大,激光在陶瓷材料加工方面的巨大潜力日趋显现。由于陶瓷材料本征的硬脆特性,使得该技术的发展中还存在许多亟待解决的问题。根据近20年有关激光宏观加工陶瓷的论文和发明专利,从加工方法的角度系统地总结分析了激光加工陶瓷材料减少热损伤的8种常用方法,并讨论了各种方法的优缺点,在此基础上对激光加工陶瓷材料的研究现状和发展前景进行评述并提出相关建议。

Laser processing affords numerous unique advantages in the domain of ceramic materials machining with the more and more wide application of ceramic materials. However, many problems should be solved in the course of the technique development due to the inherent hard and brickle characteristic of ceramics. In this paper, research papers and patents about laser macroscopically processing ceramics during the last 20 years were summarized and analyzed. 8 types of methods on laser cutting and drilling ceramics, which can reduce thermal scathe, are analyzed and summarized in detail from the point of view of processing metheds. Advantages and disadvantages of these methods are also discussed. Finally, the future of the development for laser processing ceranfic technique is estimated.
