Abstract
The effect of the current pulse time on the roughness and surface continuity of the electrospark coating is studied. It is established that in the coating mode: the current pulse time is 2•10–5 s, the frequency is 250 Hz, the stress is 50 V, the roughness parameter is Rz = 80 µm, the continuity is high, but the disadvantage is the low productivity of the process.
