空心叶轮叶片做为航空发动机零件中最关键的部件，其工作环境决定了制备叶轮叶片工艺的特殊性。目前主要采用熔模铸造技术来制作，是先采用将型芯、型腔分开制作，然后再组装在一起来铸造。这样不仅制造周期长、成本费用高，而且很有可能在装配过程中出现装配误差，导致在铸造过程中容易叶片出现穿孔、偏芯等缺陷。因此，现有的制造工艺对于现代航空工业的发展已经很难适应。为此，本文基于快速成型技术和新材料的发展，提出了一种制备空心叶片整体式陶瓷铸型的新工艺。 首先，采用快速成型光固化技术制备出结构、形状复杂的整体式空心叶片光敏树脂原型，缩短了制造周期，降低了成本，提高了精度；其次，在粒径级配技术基础上，通过正交试验对陶瓷浆料流动性和各成型工艺参数进行分析，在获得最佳陶瓷浆料配方（低粘度、高固相含量的陶瓷浆料）和陶瓷铸型成型工艺方案的前提下，利用溶胶-凝胶成型技术制备出整体式陶瓷铸型素坯，经干燥、脱脂及烧结工艺处理后获得最优性能的整体式陶瓷铸型。最后，通过实验和显微扫描技术对烧结后的氧化铝陶瓷铸型标准件（标准件尺寸60mm*10mm*4mm）进行性能分析，其性能结果如下：素坯的室温抗弯强度可达37MPa、高温（1550℃）抗弯强度最低也能达到10MPa、陶瓷密度2.65g/cm3,干燥收缩率能控制在0.7%以下、烧成收缩率也控制在0.6%以下、总的收缩率能控制在1.2%左右，完全能满足合金浇注的要求，其研究结果对生产实际有一定的参考价值。

As aircraft engine parts, hollow impeller blades were the most critical components, its work environment determines the specific of its making process. Up to now, hollow impeller blades is made by investment casting, the procedures are: firstly, make core and concave respectively, and then assembles them together for casting. This method is not only the long cycle, but also high cost. as well as the assemble errors and holes and deflect occuring . So current process is not adaptable for development of contemporary air industrial. Therefore, a new making process is put forward for making integrated hollow impeller blades ceramic casting in this paper based on rapid prototyping technology. Firstly, the photosensitive resin prototype of integrated hollow impeller blades were made with SLA which is complex in structure and shape. Using SLA to make the prototype, the manufacturing cycle is shortened, the cost is reduced and the precision is enhanced. Secondly, based on particle size grading technique, Analyses for the flow features of ceramic slurry and forming process parameters were done by means of orthogonal test. Based on obtained optimum ratio of ceramic slurry and making processes, an integral ceramic mold was made by SEM. Finally, the prosperities of the ceramic mold were anglicized by experiments. The results show that at room temperature, the bending strength of green body was up to 37MPa, and at 1550℃, the bending strength also reached 10MPa, density of ceramic was 2.65g/cm3, drying and firing shrinkage rate can be respectively controlled under 0.7%, 0.6%, and the total shrinkage rate was about to reach 1.2 %. It can meet the requirements of casting alloys. The results is of certain reference value for actual production.
