摘要
研究了内腔形状比较复杂的涡轮叶片铸件脱芯方法。结果表明 :在化学腐蚀法脱芯的基础上辅之以高压喷水设备 ,可以较有效地清除叶片内通道的残芯 ,通过试验得出了合适的工艺参数。
A de core method for hollow turbine blades having complex inner cavity has been studied It is showed that the combination of a high pressure water jeting method with the original chemically etching method may effectively eliminate the residual core in the inner passage of blades The suitable processing parameters are obtained by a series of experiments
