Abstract

Inventia se refera la un procedeu pentru realizarea formelor de turnatorie, prin vidare, utilizate, în special, la realizarea sîrmelor din aliaje pe baza de cobalt, destinate încarcarii sau placerii, prin sudare, a pieselor metalice din constructia de masini. Procedeul consta din vopsirea prin impregnare, a cavitatilor formei de turnare, prin crearea unei depresiuni de aproximativ 0,4N/cm la 2 în forma de turnatorie. Pentru realizarea formei se utilizeaza nisip caurtos, bentonita si praf de carbune, iar pentru vopsire se utilizeaza polistiren dizolvat în acetat de etil sau tetraclorura de carbon.
