摘　　要：通过对水淘析法的原理分析 ,运用流体力学中的摩擦数群法确定了以陶瓷夹杂物在水中的沉降速度来确定水流速度 ,及在确定的水流速度下 ,所能淘析出的FGH95合金粉末的最大尺寸 ;并以比较淘析出的FGH95合金粉末的实际最大尺寸与理论最大尺寸 。The principle of water elutriation process was discussed.The water flowing velocity was calculated by ceramic dropping velocity in the water by means of the frictional numeral groups method, and the maximum size of FGH95 alloy powder elutriated was determined under certain water flowing velocity. In order to justify the efficiency during the water elutriation process of separating ceramic inclusions from FGH95 alloy powder, the maximum theoretical and experimental size of FGH95 powder elutriated was compared at different water flowing velocity.
