Method for additive manufacturing of ceramic microsphere reinforced precursor ceramic
The invention relates to a method for additive manufacturing of ceramic microsphere reinforced precursor ceramic, and belongs to the technical field of silicon-based ceramic forming. The forming method comprises the following steps: balling an organic silicon precursor by an emulsion method, putting the balled organic silicon precursor into a tubular furnace, and performing pyrolysis under the protection of nitrogen or argon atmosphere to obtain ceramic microspheres; secondly, mixing ceramic microspheres, an organic silicon precursor, a reactive diluent and a photoinitiator to obtain uniformly dispersed slurry; and printing a ceramic green body with a complex shape by using additive manufacturing equipment, and carrying out post-treatment to obtain the silicon-based composite ceramic. The method is simple and low in cost, and the mechanical property of the precursor ceramic can be obviously improved.
本发明涉及一种增材制造陶瓷微球增强先驱体陶瓷的方法，属于硅基陶瓷成型技术领域。本发明的成型方法，首先将有机硅先驱体乳液法成球后置于管式炉中，氮气或氩气气氛保护，热解得到陶瓷微球；其次，将陶瓷微球、有机硅先驱体、活性稀释剂、光引发剂混合，得到分散均匀的料浆；然后利用增材制造设备打印复杂形状的陶瓷坯体，后处理后制得硅基复合陶瓷。本发明方法简单，成本较低，可明显改善先驱体陶瓷的力学性能。
