Abstract

To provide the strengthening of diamond-diamond and silicon bond powder systems are first heated to a temperature not enough to melt silicon, maintained at this temperature for 40–60 s, to provide diamond diamond strengthening and toughness of the composite material (20–25%). , then the system is heated to a temperature sufficient to melt silicon. The material obtained by using a two-stage sintering method (AKTM) is characterized by high strength and has many applications
