Laser machining of ceramics with controlled microstructure

这项研究的长期目标是通过激光辐射去除材料或通过激光焊接将部件连接起来，从陶瓷中制造出形状。工程陶瓷具有高耐热性、高硬度和化学稳定性等机械和物理性能，使其独特地适合于许多工业应用。然而，由于陶瓷又硬又脆，很难用传统方法进行加工。激光加工允许在陶瓷中制造微尺度特征，同时提供非接触技术的好处。

The long-term goal of this research is fabrication of shapes from ceramics through material removal by laser radiation or through joining of components by laser welding. Engineering ceramics possess mechanical and physical properties such as high thermal resistance, hardness and chemical stability, making them uniquely suitable to a number of industrial applications. However, being hard and brittle, ceramics are difficult to machine using conventional methods. Laser machining allows fabrication of microscale features in ceramics while providing benefits of a non-contact technique.
