Abstract:
Results on a nanoparticle collision with a target calculated by the molecular dynamics method are presented. The first problem being solved is a nanoparticle collision with a target under the conditions of cold gas-dynamic spraying. The second problem deals with nanoparticle extension, which adheres to the target due to the collision. It is shown that a chemical bond between the nanoparticle and target due to the collision. The bond in the case of titanium nanoparticle impingement onto an aluminum target is found to be stronger than that in the case of aluminum nanoparticle impingement onto a titanium target. The reason is that the titanium nanoparticle penetrates into the aluminum target to a greater depth.
