Abstract
The shape change of deposited rod with processing time has been numerically calculated by mass balance on the deposit surface between sprayed and deposited material. Local growth velocity of deposit surface is function of the surface geometry at a given position and processing time. The shape of the deposit calculated by assuming parallel spray density and normal distribution shows a reasonalbly good rod form. The radius of the rod is propotional to square root of melt flow rate, and inverse to square root of substrate withdrawal velocity.
