Abstract
Inventia se refera la procedee de activare a aliajelor, in particular la procedee de activare a suprafetei aliajelor dure cu continut de wolfram pentru lipire la temperatura joasa. Procedeul, conform primei variante, include activarea electrochimica a suprafetei aliajului cu un electrolit, ce contine, g/l: NaOH 25…200NaNO3 25…200la o densitatea curentului electric de 1…100 Ŕ/dm2 si temperatura de 20…25° Ń. Procedeul, conform variantei a doua, include activarea electrochimica termica a suprafetei aliajului cu un electrolit, ce contine, g/l:NH4Cl 100NH4OH 50 la tensiunea pe electrozi de 150…220V, densitatea curentului electric de 1…2 Ŕ/dě2 si temperatura anodului de 750°Ń.Procedeul, conform variantei a treia, include activarea electrochimica termica a suprafetei aliajului cu un electrolit, ce contine, g/l:NH4Cl 110NH4NO3 110 latensiunea pe electrozi de 150…220V, densitatea curentului electric de 1…2 Ŕ/dě2 si temperatura anodului de 750°Ń.
