The structure and properties of carbon nanomaterials including the carbon nanotubes (CNT) depend largely on the character of catalytic particles, on which the CNT formation and growth occur. A fundamental investigation on the surface modification of reactor-alloys’ samples is carried out in the work for the goal to provide catalytic properties to the surface for the formation of a dense and uniform CNT film. The island coating of nickel particles is deposited on the substrates by the method of chemical reduction of metals in aqueous solutions. The uniformity of CNT distribution over the substrates’ area depends of their surface purity. The values of surface microhardness of the modified samples increase, depending on the thickness of CNT coating, and reach the maximum values at the temperature of pyrolysis (700?C) and after annealing at 900?C.
