Abstract

This paper presents preliminary results of ion sputter erosion characterization of carbon nanotubes. Relative erosion rates were compared by exposing multiwall carbon nanotubes (MWNTs), polycrystalline diamond films, amorphous carbon, and boron nitride to the exhaust plume of a 1.5-kW Hall-effect thruster operating on krypton propellant. Two types of MWNTs were investigated: films composed of vertically aligned tubes and those horizontally laid on the substrate surface. Only diamond films and vertically aligned MWNTs survived erosion by 250-eV krypton ions. The vertically aligned tubes were found to bundle at their tips into nanocones after ion erosion.
