Method for casting ceramic slurry for ceramic core of hollow blade
The invention discloses a method for casting ceramic slurry for a ceramic core of a hollow blade, belongs to the field of ceramic slurry materials for ceramic cores, and aims to improve the high temperature and heat dissipation performance of each part of an aero-engine. The method comprises the following steps: preparing a plasticizer which at least comprises polyethylene resin and is used for improving the high-temperature performance of ceramic slurry; the plasticizer is mixed with oleic acid, white corundum powder and quartz powder to prepare the ceramic slurry. And the complex isometric crystal nickel-based superalloy hollow casting blade with the turbulent flow column and large inner cavity size change can be produced, and the impact of nickel-based superalloy liquid can be borne.
本发明的铸造空心叶片的陶瓷型芯用陶瓷浆料的方法，属于陶瓷型芯用陶瓷浆料材料领域，提高航空发动机各部件乃高温和散热性能的技术问题。该方法包括：配置增塑剂，所述增塑剂至少包括聚乙烯树脂，提高陶瓷浆料乃高温性能；所述增塑剂与油酸、白刚玉粉和石英粉混合以制备所述陶瓷浆料。能够生产出带有扰流柱的内腔尺寸变化大的复杂等轴晶镍基高温合金空心铸造叶片，且能承受镍基高温合金液冲击。
