Abstract

The paper explains the mechanisms whereby components in the diamond - (Fe-Cu-Ni-Sn-CrB2) system and products of their interaction influence the micro- and nanostructure as well as mechanical properties of the composites sintered in molds in a muffle furnace followed by hot pressing. The p–t parameters of hot post-pressing that provide decarburi-zation in the diamondmatrix transition zone by forming Fe3C, Cr3C2, Cr7C3 and Cr1,65Fe0,35B0,95 layers are determined. The wear resistance of these composites is three times as high as that of the samples produced from feedstock without chromium diboride.
