Charged micro particles (macrons) of nickel or artificial diamond were implanted to the silver films evaporated on the silicon and polished stainless steel discs. Craters were formed on the materials by collisions of the macrons. The macrons are electrostatically charged on two planar electrodes at 30 kV, extracted through the central hole in one of the electrodes and accelerated at 100 kV to the target materials. The craters and the macrons were evenly distributed on the silver film to which nickel macrons had been implanted. Diamond macrons were stuck to the stainless steel and covered the surface. The velocity of a diamond macron of 1/4 μm in diameter was estimated to be 1 to 3 km/s under an assumption that the charge of each macron is in the range 103–104e. The velocity is sufficient to cause not only plastic deformation, but impact damages such as craters for silver and stainless steel.
