PROCESS FOR OBTAINING SILVER-NICKEL-GRAPHITE AND SILVER-COPPER-GRAPHITE SINTERED CONTACTS
Inventia prezinta un procedeu de obtinere a contactelor electrice sinterizate din argint-nichel-grafit si argint-cupru-grafit cu compozitii procentuale gravimetrice: 55...96,5% Ag, 0,5...40% Cu si 1...5%C, destinate echiparii unor întrerupatoare de protectie de joasa tensiune. Pulberile de Ag, Ni, C...

| description | Inventia prezinta un procedeu de obtinere a contactelor electrice sinterizate din argint-nichel-grafit si argint-cupru-grafit cu compozitii procentuale gravimetrice: 55...96,5% Ag, 0,5...40% Cu si 1...5%C, destinate echiparii unor întrerupatoare de protectie de joasa tensiune. Pulberile de Ag, Ni, C respectiv de Ag, Cu si C amestecate mecanic, se siteaza, se granuleaza uscat sau cu ulei, se preseaza, se sinterizeaza si se calibreaza la forma si dimensiunile dorite. Procedeul, conform inventiei, permite realizarea unor contacte electrice cu siguranta sporita la curenti de scurtcircuit si cu rezistenta crescuta la uzura în arcul electric. |
