To date there is no universally recognized notions on diamond structure formation from gas phase. The set of fragments, determining this process is distinguished for different methods of activation. The information on elementary processes of interaction of hydrogen and hydrocarbon molecules with surface for activation and deposition can be found in the literature, but it is scarce. Scientific problems of thermal activation relate not only to carbon structure synthesis; the description of nonequilibrium processes in channel flows with heterogeneous chemical reactions has unquestionable importance. In this review the modern state of studies of interaction of hydrogen and methane molecule and their fragments with high temperature tungsten surfaces and diamond surfaces at the temperature close to 1300 K is considered, and accessible results are presented.
