摘要：

The bombardment process of a single tungsten atom on a tungsten nanoparticle was simulated by molecular dynamics. Projectile tungsten atoms ranging from 50 eV to 50 keV were injected into tungsten nanoparticles with diameters ranging from 2 to 12 nm. The sputtering of the nanoparticles and the retention of projectiles were found to be relative to the nanoparticle size and projectile energy. The axial direction of the nanoparticles also influenced the sputtering to some degree. The results are useful in understanding the behavior of tungsten nanoparticles generated in nuclear fusion devices.
