Abstract—The authors used selective laser melting of heat-resistant nickel alloy powder to assess applicability of additive technologies to deposition of nickel coatings on titanium substrate. Structure, element and phase composition of the coating was analyzed, revealing a multi-phase nature of the coating. Titanium atoms were detected in main phases of the coating, indicating diffusion saturation of sintered layer with elements of the substrate. Using methods of scanning electron microscopy sub-microcrystalline grains were found in the formed structure, owing to high-speed laser melting of the metal. Nano-dimensional particles of the second phase, which improve strength of the coating, are detected in the material and on edges of grains and sub-grains.
