Abstract
Metal and/or partial metal dentures having a surface modified by a pulsed electron beam system. The system includes an explosive emission cathode, an accelerating gap formed by the cathode and plasma anode, and an electron collector where the metal and/or partial metal dentures are fixed, and placed into a magnetic field. The surface of the modified metal and/or partial metal denture has high reflectance like a mirror polished surface and high corrosion resistance.
Claims18
A method for forming dentures, comprising the steps of:
- generating electron beams;
- and
- directing the electron beams to an at least partially metal substrate having the form of teeth to provide the substrate with at least one polished, amorphous surface.
