Estimation of influence of interaction of carbon with compound of carbides, borides, nitrides, silicides on structure and properties of composites Diamond-Fe-Cu-Ni-Sn
In the elasticity theory framework, the expression has been derived for the energy required for joining the carbon atom in the crystal lattice of carbides, borides, nitrides, silicides of transition metals Ti, V, Cr Mo, Nb, Hf, Cr, W and Zr, silicon compounds and boron, in order to assess their cont...

Energy Technologies & Resource Saving| Zusammenfassung: | In the elasticity theory framework, the expression has been derived for the energy required for joining the carbon atom in the crystal lattice of carbides, borides, nitrides, silicides of transition metals Ti, V, Cr Mo, Nb, Hf, Cr, W and Zr, silicon compounds and boron, in order to assess their contribution to the structure and properties of diamond-containing composite material (DCM) Fe-Cu-Ni-Sn. It is found that adding CrB2 to the initial composition Diamond - 51% Fe-32% Cu-9% Ni-8% Sn, in contrast to other additives of refractory compounds, provides a complete decarbonization in the diamond-matrix transition zone by formation of the Cr3C2, Cr7C3 and Fe3C nanoscale (5-40 nm) thickness layers and significant increase in wear resistance of DCM. By combining the obtained formulas with the methods of the physical material science, the parameters and p-T-t conditions of final squeezing of the diamond-containing composite that provide the higher physical and mechanical properties of DCM as compared with the industrial technologies |
