Production of Diamond−(Fe−Cu−Ni−Sn) Composites with High Wear Resistance

  • Published:
Powder Metallurgy and Metal Ceramics Aims and scope

It is established that structured phase formation in the diamond–(Fe–Cu–Ni–Sn) composite proceeds in the sequence different from that determined by the known phase diagrams. Depending on the processes of hot recompaction, the diamond−matrix transition zone attains a hierarchical structure and fully decarburizes through the formation of 5–40 nm Fe3C layers, thus enhancing the mechanical properties of the composite.
