Method and device for the thermo-ionic treatment of a material in order to change its physiochemical properties

摘要

the device comprises: a substrate (8) having a first (10) and a second (6) opposite faces, the first face being covered with a film of a dopant (12) and is able to be prepared in relation to the material (14) in a space (18) between the film and the material; source (2) generating a collimated laser beam (4) and pulsed to a given wavelength.the second face of the substrate held in the transparent wavelength, the laser beam is able to interact with the drug to form film of dopant ions of dopant material, and electrical means (20, 22) for generating pulse simultaneously to the asher.(a) in the space electric field to accelerate the ions of the dopant implant to the thermo ionic in the material.;application to the treatment of metals and alloys.
