Abstract

Istraživanja kuta kvašenja na legurama titanija vrlo su raširena te se titanij često koristi kao biomaterijal ili se prevlači tankim tvrdim prevlakama u svrhu poboljšanja triboloških svojstava. U oba slučaja je u kontaktu s kapljevinom te je važno poznavati svojstva kvašenja. Dan je pregled dosadašnjih istraživanja u pogledu kuta kvašenja na površinama legura titanija. U eksperimentalnom dijelu rada ispitivana su svojstva kvašenja na leguri Ti6Al4V nakon obrade laserski snopom. Praćeno je ponašanje kuta kvašenja nakon 20 i 60 sekundi pri nagibima od 0°, 30° i 60°. Izmjereni su parametri hrapavosti te su površine uzoraka analizirane skenirajućim elektronskim mikroskopom.

Abstract (english)

Contact angle studies on titanium alloys are very common today because titanium is frequently used as a biomaterial or coated with thin hard coatings for the purpose of improving tribological properties. In both cases it is in contact with the liquid and it is important to know the contact angle properties. An overview of previous research regarding wetting on the surfaces of titanium alloys is given. In the experimental part of the paper, the contact angle properties of Ti6Al4V alloy after laser treatment were studied. The behavior of the contact angle after 20 and 60 seconds at inclinations of 0°, 30° and 60° was monitored. Roughness parameters were measured and sample surfaces were analyzed with a scanning electron microscope.
