On the structure formation of diamond-containing composites used in drilling and stone-working tools (A review)

Аннотация

The publications on the studies of structures and properties of diamond-containing composites (diamond–(WC–Co), diamond–(Fe–Cu–Ni–Sn), diamond–(Co–Cu–Sn) and diamond–hard alloy plates used to produce tools for drilling oil and gas wells as well as stone-working tools have been analyzed. Particular attention has been given to the structure formation of the diamond–matrix transition zone, mechanical and operating properties of the composites. The promising lines of the development of the materials science of diamond-containing composites used in rock destruction tools have been defined.
