Times New Roman 12 pt, bold, single-line spacing, left-aligned text) The innovative method of the nanocomposite materials manufacturing has been developed, in which the SLM (Selective Laser Melting) technique is used. Nanocrystalline TiC and TiB2 powder, obtained in non-hydrolytical sol-gel synthesis and 316L stainless steel have been applied in SLM process. In present work, the composition, structure of obtained composites, along with the results of morphology, hardness measurements and oxidation resistance have been presented. During investigation the following analytical techniques have been applied: XRD, TEM, TG-DSC-MS, SEM and nanoindentation. In addition nanoindentation results has been compared with FEM model.
