Improvement of performance properties of products by surface treatment of materials with cathode spots of vacuum arc discharge

It is shown that the impact of cathode spot of vacuum-arc discharge on the plastically deformed surface may be partially or fully recovered her form. This effect was detected during vacuum-arc cleaning of the inner surface of the cylinder. Mathematical and experimental modeling of the process of restoring the inside diameter of the cylinder confirmed the effect of shape recovery upon exposure of the cathode spots of a vacuum arc on the surface.
