连续纤维增强金属基复合材料研究进展及其激光熔覆

Research Progress on Continuous Fiber-Reinforced Metal Matrix Composites and Their Laser Cladding

对连续纤维增强铝基、镁基和钛基复合材料的制备方法、微结构与性能进行了综述,指出了存在的问题,提出了激光熔覆纤维增强金属基复合材料的新方法,即将纤维预置包埋在合金粉末中,然后进行快速激光熔覆。该方法能精确控制过程参数,大幅减少制备时间,可获得性能优异的复合材料。

The preparation methods, microstructures and properties of continuous fiber-reinforced aluminum, magnesium and titanium matrix composites are summarized. The existing problems are pointed out and a new method of preparing the fiber reinforced metal matrix composites by laser cladding is put forward. The fibers are embedded into the cladding powder first and then processed by laser cladding rapidly. This method can precisely control the processing parameters, reduce the processing time, and make the composites with a better performance be obtained.
