Single crystal ceramic core preparation process for aero-engine blade and depoling detection equipment
The invention relates to the field of aero-engine manufacturing, in particular to a ceramic core preparation technology of an aero-engine worm wheel blade and core removal detection equipment. The invention provides a preparation process of a single crystal ceramic core for an aero-engine blade. The preparation process comprises the following steps: S1, ball-milling and mixing corundum powder, activated aluminum oxide and gadolinium oxide graphite powder; s2, heating a plasticizer with the weight percentage of 15-20% to 60-70 DEG C, gradually adding the plasticizer into the ball mixture in the S1, and continuously stirring to prepare an aluminum oxide ceramic core reinforcing material; s3, the ceramic core is buried in a mold through aluminum oxide, and pre-sintering is conducted; and S4, the pre-sintered ceramic core is taken out, and final sintering is carried out. The gadolinium oxide is doped into the slurry for preparing the ceramic core, and the gadolinium oxide has the radioactive characteristic, so that the radioactivity in an alloy casting can be conveniently detected in the subsequent depoling process, and then whether the depoling of the alloy casting is complete or not is judged.
本发明涉及航空发动机制造领域，具体涉及航空发动机蜗轮叶片的陶芯制备工艺、脱芯检测设备。本发明提供了一种航空发动机叶片用单晶陶芯制备工艺，包括如下步骤：S1、将刚玉粉、活性氧化铝、氧化钆石墨粉进行球磨混合；S2、将重量百分比为15%～20%的增塑剂加热至60～70℃，逐步加入S1中的球混料中，并继续搅拌，制成氧化铝陶瓷型芯增塑料；S3、采用氧化铝将陶瓷型芯填埋于模具中，并进行预烧；S4、将预烧后的陶瓷型芯取出，并进行终烧。通过在制备陶瓷型芯的浆料中掺入氧化钆，由氧化钆具有放射性的特性，可方便在后续脱芯的过程中，对合金铸件中的放射性进行检测，进而判断合金铸件是否脱芯完全。
