采用分子动力学方法模拟不同入射角下纳米级陶瓷颗粒对衬底的冲击，探讨气溶胶沉积法的机理。与正常入射情况相比，斜入射的粒子在衬底上呈现出不同的破碎特征，包括粒子在衬底上滚动和沉积原子的尾部结构。在衬底上也观察到结构的改变及其与入射角的关系。纳米颗粒和衬底温度的升高随入射角的变化而变化。
Impacts of nanometer sized ceramic particles to the substrate with different incident angles were simulated by molecular dynamics to investigate the mechanism of aerosol deposition method. Comparing with the normal incident case, obliquely incident particles to the substrate show different characteristics of fragmentation including particle rolling on the substrate and a tail structure of depositing atoms. Structural modification and its incident angle dependence were also observed in the substrate. Elevations of temperatures in nanoparticle and substrate show different dependencies on the incident angle.
