Abstract
Invenţia se referă la domeniul construcţiilor de maşini, şi poate fi utilizată în industria constructoare de turbine aeronautică şi energetică la repararea paletelor sau a altor părţi ale turbinelor, în special la eliminarea acoperirilor rezistente la căldură de pe o suprafaţă din aliaje dure.Procedeul de eliminare a acoperirilor rezistente la căldura de pe o suprafaţă din aliaje dure include prelucrarea piesei în regim electrolitic cu plasmă folosind curent cu impulsuri cu o frecvenţă de alimentare de 50Hz. Prelucrarea piesei se efectuează cu impulsuri bipolare cu o durată de 10...50 µs pentru componenta anodică, şi de 40...200 µs pentru componenta catodică.
