喷射成形工艺能够以较少的工序生产整体致密、成分均匀、晶粒细化、力学性能优良的坯件， 但控制喷射成形过程的独立工艺参数却较多， 给工艺优化带来困难。结合所建立的３Ｄ 形状模型，针对两种不同运动方式的沉积器， 探讨了喷射熔滴质量流率沿雾化锥的轴向及径向的空间分布， 研究了雾化压力、沉积距离、沉积器下降速度、偏心距及倾斜角对高温合金沉积坯形状及致密度的影响。研究结果表明， 通过计算机辅助优化工艺参数后， 可以获得所需形状的、致密的沉积坯 The injection molding process can produce the whole compact, uniform composition, grain refinement, excellent mechanical properties of the blank in fewer steps, but the independent process parameters to control the injection molding process are more, to process optimization difficult. Combined with the established 3D shape model, the spatial and spatial distribution of mass flow rate of sprayed droplet along the axial and radial distribution of atomizing cone was discussed for two kinds of depositors with different movement modes. Atomization pressure, deposition distance, deposition Effect of Decline Speed, Eccentricity and Inclination Angle on Shape and Density of Superalloy Deposition Billet. The results show that, by computer-aided optimization of process parameters, you can get the desired shape of the dense blank
