  • Method for making an AlO—cBN composite
    Patent number: 10858292
    Abstract: Conventional sintering processes convert a portion of cBN to hBN which is softer than cBN which negatively affects functional properties of an alumina composite. The invention is directed to method for making an alumina-cubic boron nitride (Al2O3-cBN) composite that contains substantially no hexagonal boron nitride (hBN) by non-conventional spark plasma sintering of cBN with nano-sized alumina particles. The invention is also directed to Al2O3-cBN/Ni composites, which contain substantially no hBN, and which exhibit superior physical and mechanical properties compared to alumina composites containing higher amounts of hBN.
    Type: Grant
    Filed: July 10, 2019
    Date of Patent: December 8, 2020
    Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS
