Development of PcBN composites by spark plasma sintering technique
2023O PcBN (“Polycrystalline cubic Boron Nitride”) é um material densificado por técnicas HPHT e possui um elevado custo económico. Neste trabalho pretendeu-se estudar o comportamento durante a sinterização de cBN-TiCN-Ni e a possibilidade de densificação pela técnica de Sinterização Assistida por Campo Elétrico (SPS – “Spark Plasma Sintering ...

Wirkmechanismen beim Schleifen von PcBN mit Mehrachskinematiken
Diese Dissertation konzentriert sich auf das Schleifen von polykristallinem Bornitrid (PcBN) mit Diamantschleifwerkzeugen und die Entwicklung effektiver Strategien zur Herstellung komplizierter Schneidwerkzeuggeometrien. Zunächst werden die Einflüsse der Prozesskinematiken auf die geometrischen Prozessgrößen der Schleifprozesse beschrieben. Nachfolgendopenaire +1 more source

The experimentally-rated method of modeling of porous and grain structures of cubic boron nitride composites, which obtain by reactionary sintering with preimpregnation by aluminium under pressure is proposed. Possibility of process control of aluminium dispersing in a mixture at an impregnation stage under pressure is shown.
