Abstract

L'invenzione riguarda un vaporizzatore ad arco voltaico comprendente un anodo (1), un supporto (2) per il pezzo da rivestire, un gruppo catodico con un catodo da evaporare a forma di disco (3), un portacorrente (4) e uno schermo principale (5), che circonda la superficie laterale del catodo (3). L 'altezza del catodo (3) è inferiore al suo diametro per lo meno di quattro volte, il portacorrente (4) è a forma di tazza e si trova a contatto elettrico con la superficie del catodo (3) non soggetta ad evaporazione, e il catodo e il portacorrente sono circondati da uno schermo aggiuntivo magnetico.Fig. 1.
