激光快速成形技术制备Al/SiC复合材料在工艺上存在许多难点 ,这是由Al/SiC复合粉末的特性及激光加工的特点所决定的。具体的工艺参数包括基体材料的选择及处理、激光功率、扫描速度、送粉量、载气量等。其变化均可以影响最终的成形质量。本文通过大量的试验 ,总结了工艺参数对Al/SiC复合材料激光快速成形过程的影响 ,并得出普遍适用的规律 ,对进一步的工作有重要的指导意义 Laser rapid prototyping technology in the preparation of Al / SiC composites in the process there are many difficulties, which is based on the characteristics of Al / SiC composite powders and laser processing characteristics of the decision. Specific process parameters include the choice of substrate material and processing, laser power, scanning speed, powder feeding, carrier gas and so on. The changes can affect the final forming quality. This article through a large number of experiments, summed up the process parameters on Al / SiC composite laser rapid prototyping process, and come to universal law, for further work has an important guiding significance
