Method for smoothing and polishing metals via ion transport free solid bodies and solid bodies for performing the method

1. A method for smoothing and polishing metals via ion transport by free solid bodies, the method comprising:

connecting a part to be treated to a positive pole (anode) of a current generator; and

subjecting the part to friction with a set of particles comprising electrically conductive free solid bodies charged with a negative electrical charge in a gaseous environment.

2. The method of claim 1 , further comprising:

positioning the part within a receptacle, wherein the set of particles is disposed within the receptacle and electrically contacts a negative pole (cathode) of the current generator.

3. The method of claim 2 , wherein the receptacle is electrically connected to the negative pole of the current generator such that the electrical contact of the particles with the negative pole of the current generator is carried out through the receptacle acting as the cathode.

4. The method of claim 2 , wherein a ring disposed in the receptacle is electrically connected to the negative pole of the current generator such that the electrical contact of the particles with the negative pole of the current generator is carried out through the ring acting as the cathode.

5. The method of claim 1 , further comprising:

securing the part to a securing element coupled to a device capable of moving the part relative to the set of particles, wherein the friction between the part and the set of particles results from motion of the part imparted by the device.

6. The method of claim 5 , wherein the motion imparted to the part by the device is an orbital motion about an axis and on a plane and, simultaneously, a rectilinear and alternative motion in a plane perpendicular to the orbital motion.

7. The method of claim 1 , wherein the gaseous environment occupying interstitial space between the particles is air.
