This paper deals with a state-of-the-art two staged coating technology involving Cold Gas Dynamic Spraying (CGDS) followed by treatment of the sprayed layer by Micro Arc Oxidation (MAO). This technology provides good physical and mechanical properties and high performance of coatings obtained. Experimental study data on the used process parameters and their impact on the performance of obtained coatings are presented. Test data relating to the properties of the coatings obtained, and general technological recommendations on practical application of the proposed technology are provided. U radu sa razmatra najsavremeniju dvostepenu tehnologiju nanošenja premaza koja uključuje dinamički sprej hladnog gasa (CGDS) praćen tretiranjem nanetog sloja spreja mikro-lučnom oksidacijom (MAO). Ova tehnologija daje dobre fizičke i mehaničke osobine i visoke performanse dobijenih premaza. Predstavljeni su eksperimentalni rezultati istraživanja parametara ovih procesa i njihov uticaj na performanse dobijenih premaza. Dati su rezultati testiranja svojstava dobijenih premaza i opšte tehnološke preporuke o praktičnoj primeni predložene tehnologije.
