Abstract
Invenţia se referă la tehnologia protecţiei electrochimice a metalelor în medii naturale şi artificiale, şi anume la electrozii utilizaţi în calitate de anozi pentru protecţie catodică anticorosivă a construcţiilor metalice subterane.Esenţa invenţiei constă în formarea pe o eboşă din oţel carbon nealiat a unui strat superficial cu solubilitate redusă. Procedeul include depunerea galvanică pe eboşă a unui strat intermediar de nichel cu grosimea de 110…150 µm, iar apoi, prin metoda alierii prin scântei electrice, formarea unui strat superficial compus din intermetalide titan-nichel, carburile respective şi grafit, cu un conţinut total de carbon de 6…11% mas. de la masa stratului superficial.Rezultatul constă în reducerea de cca 2,1 ori a costului fabricării anodului puţin solubil pe suport de oţel, comparativ cu analogul proxim pe suport de titan, cu menţinerea rezistenţei înalte a anodului contra coroziunii chimice şi electrochimice.
