Abstract
Inventia se refera la un procedeu de stanare electrochimica a suportului metalic al lagarelor de alunecare cu frecare lichida, obtinând un strat aderent si uniform de 7...10 nium, necesar turnarii aliajului antifrictiune. Inventia apartine domeniului acopriri metalice. Procedeul, conform inventiei, consta din urm,atoarele: suportul metalic al lagarului de alunecare cu frecare lichida se degreseaza, se spala, se decapeaza, se spala, apoi se staneaza electrochimic în solutia pe baza de sulfat stanos, sulfat de sodiu, acid sulfuric, acid fenolsulfonic si nonilfenoletoxilat la temperatura mediului ambinat, timp de 3...5 min.
