Diamonds with carbon coating

Diamonds with carbon coating

This functional material is intended for the development of the mechanical and thermal sustained metal – diamond and metal - dielectric types of composite materials, with various physical and chemical properties.  

The coating of the diamond with various carbides allows to resolve two important  issues: to provide the necessary wettability between the materials of matrix and reinforcement and to disable the unwanted chemical reaction between materials of matrix and reinforcement.

Depending on the matrix material, to ensure of maximum wettability, it is possible to use various types of carbides – WC, MoC, TiC, B4C
