This paper describes surface modification and surface deposition using a high-peak current discharge in an air gap and describes the relation between capacitance, which determines the peak current, and the deposition rate. The process is controlled manually using a rotating tool. The discharge circuit is a resistor-capacitor (RC) circuit, and switching is executed by means of a thyristor. The deposition of nickel onto a steel surface was performed using a nickel-based alloy for the electrode. The electrode was controlled with reciprocating rotation. The influence of the capacitance of the capacitor and the diameter of the electrode on the deposition rate was investigated. Using the proposed method, excellent surface deposition was achieved.
