Abstract

In order to study the influence of discharge parameters on the electric spark deposition process, an automatic electric spark deposition device is built by a closed-loop control system of discharge parameters. An automatic electric spark deposition test is carried out at different control voltages. By analyzing the effective discharge waveform parameters, transfer efficiency, deposition efficiency, contact force in the deposition process, surface morphology, and cross-sectional morphology of the deposition layer under different control voltages, etc. Analysis of the results shows that changing the control voltage has a direct effect on the number of discharge types in the deposition process. With the appropriate control voltage, better transfer efficiency and deposition quality can be achieved. Contact discharge has a greater effect on material transfer efficiency than other types of discharge. The transfer of the electrode to the material on the workpiece is mainly achieved by contact discharge. Automatic control of discharge parameters can also be applied to automatic control of discharge pulse types.
