Composite Materials Based on Cubic Boron Nitride: Structure and Properties

Creation of Superhard Composite Materials Based on Diamond and Boron Nitride

“…The task is to create a superhard composite material that provides an expansion of its range of applications by varying its composition and properties, for example, strength, hardness, wear resistance and other mechanical properties, as well as a method that makes it relatively easy to obtain such a material [14][15][16].…”

Effective Work Function of Cathodes Consisting of Cubic Boron Nitride and Aluminum Nitride

“…Composite cathodes made of high pressure sintered c-BN-AlN show promise for control of their thermal electronic emission properties. Furthermore, the synthesis processes of c-BN, AlN, and their composites are well understood [6][7][8]. The known lack of evidence of active chemical interaction between highly dispersed powders of c-BN and A1N, or between the elements of the composite, makes for high thermal stability cathodes over a wide temperature range up to 2100-2300 K. Process engineering of composites using semiconductor type c-BN, allows for the generation of cathodes with a smoothly controlled work function F *, owing to the alloy additives in the matrix material of the cathode.…”
