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

Abstract

It is established that structured phase formation in the diamond—Fe—Сu—Ni-Sn composition differs from the sequence determined from the known phase diagrams of the constituents. Depending on the processes of hot recompaction, the diamond-matrix transition zone acquires a hierarchical structure and fully decarbonizes via formation of 5—40 nm Fe_{3C interlayer, thus enhancing the mechanical properties of the composite.}
