Spatial carbon molecules fullerene type identified by thermal gravimetric analysis (TGA) of graphite films deposited on metal surface by electrical discharges in impulse

The formation of graphite films at micrometric and nanometric scale on the surfaces of alloys-made parts causes their diffusion in the surface layer accompanied by the formation of high hardness carbides, and, as a result, the wear resistance of this layer increases [1-5]. TGA tests on graphite films were conducted on a Du Pont Instruments 951 device. This device shown in figure 1 and 2.
