Abstract

Inventia se refera la metodele de prelucrare electrofizica a materialelor, in special la tehnologiile de durificare a suprafetelor metalice prin descarcari electrice prin impulsuri de scurta durata. Procedeul de durificare a suprafetelor metalice prin descarcari electrice consta in efectuarea descarcarilor electrice prin impulsuri intre electrodul-scula, executat in forma de disc rotitor din grafit electrotehnic, si suprafata de prelucrare a piesei, conectate la circuitul de descarcare a generatorului de impulsuri de curent. Impulsurile de curent in interstitiul dintre electrodul-scula si piesa sunt formate din trenuri a cate doua impulsuri, primul dintre ele fiind de polaritate directa cu durata de 150...200 Mys, iar cel de-al doilea - de polaritate inversa cu durata de 10 ori mai mica la aceeasi cantitate de energie degajata intre electrodul - scula si piesa. Rezultatul inventiei consta in majorarea duritatii suprafetelor metalice, in micsorarea rugozitatii suprafetei prelucrate si pastrarea geometriei piesei prelucrate.
