Abstract
Inventia prezinta un procedeu de obtinere a contactelor electrice sinterizate pe baza de argint cu adaosuri din nichel si grafit, de preferinta 0,5...30% Ni, 1...5%C si 65...98,5% Ag, procente gravimetrice, cu structura fin dispersata destinate echiparii aparatajului electrotehnic de joasa tensiune. Amestecurile de pulberi AgNiC, obtinute prin coprecipitarea chimica a argintului si nichelului, urmata de amestecarea mecanica cu grafit, se granuleaza umed cu ulei sau solutie de alcool polivinilic, se preseaza, se sinterizeaza si se calibreaza. Procedeul, conform inventiei, permite realizarea unor contacte electrice sinterizate cu caracteristici îmbunatatite fata de contactele obtinute din pulberi amestecate mecanic si permite o buna reproductibilitate pentru orice interval de compozitie.
