摘要： A material 100 for an anti-theft device is described. The material 100 comprises a binder 102, a first type of particles 104, a second type of particles 106, and graphene layer 114 between the binder and each of the first type of particles 104 and second type of particles 106. The first type of particles 104 are selected from at least one of diamond and cubic boron nitride ‘CBN’, and the second type of hard particles are selected from at least one of a metallic carbide and a ceramic material. The first particles resist a cutting action of a cutting tool and the second particles degrade the cutting tool during the cutting action. The graphene bonds the particles to the binder to prevent the particles being dislodged by a cutting action. The result of the combination of these actions is to delay the time for an operator of a cutting tool to cut through the material 100.

摘要： 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.
