In this study, accelerated ceramics particle, whose diameter is between several ten and several hundreds nano-meter order, is sprayed to the workpiece on purpose to create film. This film creation method is called nano-particle jet deposition (PJD). gas-particle flow adjacent to the workpiece is measured by the PIV and deposition dynamics is estimated utilizing the FEM and MD simulation. Conclusions of this research is as follow.・Flow rate of particle sprayed by the PJD device can be controlled between 200~310m/s. In the case the flow rate is 200~275m/s, alumina particles (diameter: 2μm) remove the soda glass.・It is found that there is transition condition from deposition to removal. And each size of particle has the different transition condition.・When the particles hit the workpiece, particles are fractured.・MD simulation indicate that the optimum flow rate is 205~275m/s.

在此螺柱中，加速的陶瓷粒子的直径在几个嫩的纳米级rpose之间创建膜，称为纳米颗粒射流沉积（PJD）。 PIV和动力学使用FEM和MD模拟，在流速为200-275m/s的情况下，氧化铝颗粒（直径：2μm）消除了苏打水玻璃粒子的过渡条件不同时，当粒子击中工件时，粒子会破裂。
