The physical process,structure and key factors of the deposition of two typical metal atoms onto carbon nanotubes were studied by molecular dynamics method. A way to improve the coating ability of metal atoms on the surface of carbon nanotubes was proposed. The results showed that the adsorption of carbon nanotubes on metals and the polymerization of metals determined the deposition of metal on the surface of carbon nanotubes. In order to make carbon nanotubes coated with more metal atoms,the deposition temperature should be increased for the metal with strong adsorption capability,while the deposition temperature should be at low temperature for the metal with weak adsorption. Moreover,the charged metal atoms could effectively promote the deposition of metal atoms with weak adsorptive capability onto carbon nanotubes.
