Description

The invention relates to mechanical engineering, in particular to electrophysical methods of processing materials, and can be used for electroerosive deposition of metals on conductive parts.

The purpose of the invention is to increase the productivity of the process of electroerosive doping by increasing the electrode density of the multi-electrode tool.

FIG. 1 shows a device for electroerosive doping; in fig. 2 is a section A-A in FIG. one.

The device for electroerosive doping consists of a body in the form of two parallel plates 1 and 2 of dielectric material connected by spacers 3. On the plate 1, by means of unions 4, electrode holders are fixed in the form of flexible dielectric tubes 5, on the opposite end of which the alloying electrode 6 is mounted Inside

the holder causes the alloying electrode 6 to make tangential impacts on the part 11. The operating current is supplied through the current-carrying wires 8, on which the models 7 are suspended.

5 The use of the device improves the performance of the EDM doping process by increasing the electrode density of the multi-electrode tool and reducing the number of passes along the surface of the part to achieve a given coating thickness.
