Ion Beam Surface Treatment (IBEST) experiments on Sandia's new Repetitive High Energy Pulsed Power facility have demonstrated new capabilities for materials surface treatment. Tests have confirmed corrosion resistance, surface hardening, amorphous layer and nanocrystalline grain size formation, metal surface polishing, controlled melt of ceramic surfaces, surface cleaning and oxide layer removal. IBEST uses high energy pulsed (60-200 ns) ion beams to directly deposit energy in the top 2-20 micrometers of the surface of materials. Deposition of beam energy in a thin surface layer allows melting of the layer with relatively small energies (1-5 J/cm2) and allows rapid cooling (109 K/sec) and resolidification of the melted layer by thermal diffusion into the underlying substrate.
