Sažetak

U radu su predstavljeni rezultati ispitivanja, čiji je cilj bio da se poboljšaju mehaničke karakteristike (tvrdoća i otpornost na habanje) slojeva dobijenih navarivanjem pomoću TiN i SiC nanočestica u obloženim elektrodama (SMAW-REL postupak). Dva parametra su kontrolisana variranjem uvedenih nanočestica. Obavljeno je metalografsko istraživanje odabranih uzoraka i utvrđene su promene mikrostrukture.
