Abstract

Novel superhard sinters of shock-synthesized B/C/N heterodiamond that have both the high hardness of diamond and the excellent steel-cutting capability of cubic BN have been investigated. The addition of special Ti/C/N ceramics unexpectedly made sintering possible. Surprisingly, the heterodiamond particles in the sinters showed a very unique nanoscale dispersion, meaning perfect sintering had occurred. The nanostructure-controlled sintering of the heterodiamond will open a new field of all-purpose cutting and zero-friction materials in the near future.
