Abstract
Results on a nanoparticle impact onto a target calculated by the molecular dynamics method are presented. The first problem being solved is the nanoparticle impact onto 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 impact. It is shown that a chemical bond between the nanoparticle and target is formed during the impact. The bond in the case of the titanium nanoparticle impact onto an aluminum target is found to be stronger than that in the case of the aluminum nanoparticle impact onto a titanium target. The reason is that the titanium nanoparticle penetrates into the aluminum target to a greater depth.
