【摘要】 介绍了喷射电沉积快速成形技术的基本原理,分析了金属零件成形过程中,定域性对零件成形精度的重要性,并对影响定域性的因素进行了基础实验研究。结果表明:喷嘴口径、喷嘴与阴极间的距离对定域性有密切关系,喷嘴口径小、喷嘴距离小,则定域性好,尺寸精度高;阴极电流密度和喷嘴扫描速度对定域性亦有影响,阴极电流密度低、喷嘴扫描速度快,则金属沉积斑尺寸小,定域性好。更多还原

【Abstract】 The theory of rapid prototyping based on jet electrodeposition was introduced,and importance of precision of elecrtrodeposition during fabrication of metal parts was analyzed and the fundamental experiments about the precision of electroforming spot were achieved.The results show that the size of jet nozzle and the distance of jet nozzle have great effects on the precision of electroforming spot,the high precision of electroforming spot can be gained with the small size of jet nozzle and short jet distance.Additionally,the current density and scanning velocity of nozzle also have influences on the dimensional precision.Electroforming spot and parts with high precision can be obtained with low current and high scanning velocity.更多还原
