METHOD AND DEVICE FOR TREATING A THERMO-IONIC EFFECT MATERIAL IN ORDER TO MODIFY ITS PHYSICO-CHEMICAL PROPERTIES

摘要

P Process and device for treating a material by thermo-ionic effect with a view to modifying its physicochemical properties. BR/ The device comprises: a substrate 8 comprising a first 10 and a second 6 opposite faces, the first face being covered with a dopant film 12 and being able to be arranged facing the material 14 while maintaining a space 18 between the film and the material; a source 2 generating a pulsed laser beam 4 of a given wavelength, directed on the second face of the transparent substrate at said wavelength, this laser beam being able to interact with the dopant film to form ions of dopant by explosive vaporization of said dopant, and electrical means 20, 22 for generating simultaneously with the laser pulse, a vector electric field E in said space for accelerating the dopant ions for their thermo-ionic implantation in the material. BR/ Application to the treatment of metals and alloys. BR/ (CF DRAWING IN BOPI) BR/ BR/ / P
