U ovom radu je izvršeno nanošenje hidroksiapatitnih (HA) prevlaka primenom visokoenergetskog laminarnog plazma sprej postupka. Glavni ciljevi rada su bili: (i) da se ispita uticaj nekoliko parametara procesa nanošenja na hemijska, strukturna i morfološka svojstva HA prevlaka i (ii) da se ispita uticaj ljudskih proteina albumin i gama globulin na početni stadijum procesa biomineralizacije koji se javlja na površini dobijenih HA prevlaka u modifikovanim Kokubo rastvorima (simulirane telesne tečnosti) u kojima je vrednost pH bila aktivno regulisana pomoću CO2... In the present work, hydroxyapatite coatings (HACs) were deposited by using the high power laminar plasma spray process. Major objectives were: (i) to estimate effects of several deposition parameters on chemical, structural, and morphological properties of HACs and (ii) to evaluate effects of human proteins albumin and gamma globulin on the early stage of the biomineralization process on the surface of HACs in modified Kokubo solutions (simulated body fluids) in which the pH value was actively regulated using CO2.
