Peculiarities of Structure Formation in Ni–C, Al–C, and Ni–Al–C Systems at High-Temperature Heating.

We performed high-temperature treatment of the Ni–C, Al–C, and Ni–Al–C powder mixtures (5 wt % C (soot)) up to the melting point of the respective metals and found that the melt particles coagulate with formation of Ni, Al, and NiAl (intermetallic) spherical particles, respectively. The Ni particles have almost perfect spherical shape and a multilayer graphite coating. The NiAl particles have a thin graphene (graphite) coating. [ABSTRACT FROM AUTHOR]
