Abstract
Inventia de fata prezinta un procedeu de obtinere a contactelor din W-Cu, utilizate drept contacte de rupere în întrerupatoare de medie înalta, cu performante superioare. Contactele se obtin prin metoda metalurgiei pulberilor, procedeul constând în amestecarea pulberii de W cu una din pulberile de Ni, Co sau Fe, dozate, urmate de granularea amestecului, presarea de comprimate-schelet de forma si la dimensiuni spropiate de cotele finite, sinterizarea si infiltrarea lor în atmosfera reducatoare sau în vid, cu cantitatea de Cu necesara obtinerii compozitiei finale dorite.
