Abstract:
A $\mathrm{Ni}$–$\mathrm{Al}$–$\mathrm{C}$ based composite material is synthesized by the method of electric thermal explosion under a pressure of $96$ MPa. During an electrothermal explosion in a powder reaction medium $(\mathrm{Ni}+\mathrm{Al}+\mathrm{C})$, a $\mathrm{Ni}$ and $\mathrm{Al}$ based melt is formed, in which carbon dissolves. It is shown that in the process of crystallization of the final product, carbon, due to low solubility in $\mathrm{Ni}\mathrm{Al}$, is located on the surface of intermetallic grains of $\mathrm{Ni}\mathrm{Al}$ in the form of multilayer graphite nanofilms with a thickness of $50\div80$ nm, filling the intergranular space. The microhardness of the synthesized material is $3.084$ MPa.
Keywords:
electrothermal explosion, structure formation, carbon films, intermetallic compounds.
