DEVICE AND METHOD FOR ALTERING THE CHARACTERISTICS OF THREE-DIMENSIONAL SHAPED PARTS USING ELECTRONS

The invention relates to a method for altering the material characteristics of a three-dimensional shaped part (2) using electrons. In said method, at least one electron generator (4a; 4b; 4c) generates electrons and accelerates the latter through at least three electron discharge apertures (6a; 6b;...

Beschreibung
Zusammenfassung:	The invention relates to a method for altering the material characteristics of a three-dimensional shaped part (2) using electrons. In said method, at least one electron generator (4a; 4b; 4c) generates electrons and accelerates the latter through at least three electron discharge apertures (6a; 6b; 6c), which to a great extent completely encompass the cross-section of a process chamber (7), in such a way that the entire surface, border layer or the entire volume of the shaped part (2) is bombarded by electrons as it passes through the process chamber (7). According to the invention, a first device (8; 9) controls the electron energy density that is emitted across the surface of at least one electron discharge aperture (6c), in such a way that different electron energy densities are emitted across individual sub-regions of said aperture (6c) in accordance with the geometry of the shaped part (2) and/or the position of the shaped part (2) in the process chamber (7).
