Development of Power Supplies for Electrospark Alloying with Manual Vibrating Electrode

The paper presents the main schemes based on which installations for electrospark alloying have been and are being created. Schemes of generators of spark impulses from the first relaxation RC-generators to the separated semiconductor are considered. Ways of improvement of schemes and of characteristics of the received coverings are offered. It is shown that high-frequency processing considerably improves qualitative characteristics of the deposited layers.
