AB  - The effects of picosecond Nd:YAG laser irradiation on chemical and morphological surface characteristics of the commercially pure titanium and Ti-13Nb-13Zr alloy in air and argon atmospheres were studied under different laser output energy values. During the interaction of laser irradiation with the investigated materials, a part of the energy was absorbed on the target surface, influencing surface modifications. Laser beam interaction with the target surface resulted in various morphological alterations, resulting in crater formation and the presence of microcracks and hydrodynamic structures. Moreover, different chemical changes were induced on the target materials' surfaces, resulting in the titanium oxide formation in the irradiation-affected area and consequently increasing the irradiation energy absorption. Given the high energy absorption at the site of interaction, the dimensions of the surface damaged area increased. Consequently, surface roughness increased. The appearance of surface oxides also led to the increased material hardness in the surface-modified area. Observed chemical and morphological changes were pronounced after laser irradiation of the Ti-13Nb-13Zr alloy surface.

AB  - Metallic biomaterials are most commonly used as hard-tissue replacements because of their favorable mechanical features and excellent biocompatibility. The objective of this paper is to present an overview of diverse surface modification techniques, with a special emphasis on the laser surface modification method, as well as diverse characterization techniques used for investigating the impact of the surface modification process on metallic implant materials' properties. Moreover, the effect of laser radiation on the surface its and mechanical characteristics, as well as on the structure of metallic bioimplants, is presented. The study of influence of high-intensity laser radiation on metallic materials' surface includes primarily investigations of the surface morphology modifications and specific surface structure formation since their presence enables enhanced osseointegration.
AB  - Metalni biomaterijali se najčešće koriste za izradu implantanata čvrstih strukturnih delova ljudskog tela zbog svojih dobrih mehaničkih karakteristika i odlične biokompatibilnosti. Cilj rada je da se pregledno predstave različite tehnike površinske modifikacije implantantnih materijala sa posebnim osvrtom na metodu laserske modifikacije površine, kao i mnogobrojne karakterizacione metode za ispitivanje uticaja procesa površinske modifikacije na svojstva metalnih implantantnih materijala. Osim toga, predstavljen je i razmatran uticaj laserskog zračenja na površinske i mehaničke karakteristike, kao i na strukturu metalnih bioimplantanata. Ispitivanje uticaja laserskog zračenja visokog intenziteta na površinu metalnih materijala prvenstveno obuhvata ispitivanje morfoloških površinskih promena i formiranja specifičnih površinskih struktura, koje doprinose poboljšanju oseointegracije metalnih implantanata.
