Abstract
L'invention concerne des agglomérats abrasifs. Pour unir un agglomérat abrasif de diamant ou de nitrure de bore cubique à un second agglomérat semblable ou à un support de carbure cémenté, on dépose une couche d'alliage de brasure sur une couche de métal de transition sur le premier agglomérat, on place le second agglomérat ou le support de carbure sur la couche de brasure et on chauffe l'ensemble pour unir les deux éléments. Application : obtention d'agglomérats abrasifs unis entre eux ou à un support de carbure cementé de façon très robuste par une couche d'alliage ayant un point de fusion relativement élevé.
