Abstract

Liantul metalic dur, conform inventiei este constituit din pulbere de cupru, pulbere de staniu si deseuri de carburi metalice provenite de la rectificarea placutelor sinterizate cu discuri diamantate. în scopul maririi duritatii tenacitatii si durabilitatii sculelor, liantul contine 30-75% pulbere de cupru, 5-85% pulbere de staniu, fin divizate si 5-50% agregat sinterizat, deseu de carburi metalice, macinate, cu granulatia de 63 miu m.
