多层喷射沉积技术中的轨迹分析

ANALYSIS ON THE LOCI ABOUT THE MULTILAYER SPRAY DEPOSITION

提出了多层喷射沉积在板坯和管坯方面雾化液滴沉积到接收器表面的轨迹方程，分析了各工艺参数对轨迹的影响．结果表明，各参数中ωｙ／ωｘ对轨迹分布的均匀性影响最大．当ωｙ与ωｘ之比成整数时，多层喷射沉积工艺的第二层就开始沿着第一层轨迹线重喷；但随着ωｙ／ωｘ值越大，单层轨迹越复杂；ωｙ／ωｘ值偏离倍数关系时，多层喷射沉积轨迹分布趋向均匀．

おhis paper provides the loci equations about multilayer spray deposition (MSD) plate blanks and tube blanks,and analyses the effects of each parameter on the loci.The results show that ωy/ωx is the most important effect:when ωy is the intergral times of ωx,the following layers loci are the same as the first one and distribution in the same depositions;when ωy is larger than ωx,the first layer loci is more complicated;the further ωy/ωx deviates integral,the more homogenous the loci are.
