PROCEDE POUR TRAITEMENT THERMOCHIMIQUE DE SURFACE PAR IMMERSION DANS UN PLASMA, INSTALLATION POUR CE PROCEDE, UTILISATIONS ET PIECES OBTENUES

摘要

In order, in the plasma-assisted thermochemical treatment of workpiece surfaces, to increase the surface area treated per unit time while at the same time ensuring that the surface microstructure of the workpiece treated is the same as that of an untreated workpiece, the invention calls for a low-voltage discharge (27) to be generated and the workpieces (33) to be charged up to a positive electrical potential (25) with respect to the discharge cathode (7).
