Abstract (Croatian)

Ovaj rad sastoji se od dva dijela: • Teoretskog • Eksperimentalnog U teoretskom dijelu opisana su svojstva titana i njegovih legura. Također, dan je pregled legirnih sustava, te su opisani postupci nastajanja čistog titana. Nadalje, spomenuta je i sve veća primjena titana i njegovih legura u industriji. Naglasak je stavljen na primjenu u medicini. U eksperimentalnom dijelu ispitana je korozijska postojanost legure titana Ti6Al4V u simuliranom biološkom okolišu. Pokušao se utvrditi utjecaj kloridnih iona na stvaranje pasivnog filma na površini legure. Elektrokemijskim ispitivanjima ispitana je njena sklonost rupičastoj koroziji te je na kraju dan zaključak cijelog eksperimenta.

Abstract

This work consists of two parts: • Theoretical • Experimental In the theoretical part, properties of titanium and his alloys are described. Also, an overview of the bonding systems is given with the description of the procedures needed to create pure titanium. Furthermore, the rising use of titanium and his alloys in the industry is mentioned. Emphasis is placed on the use of titanium in medicine. In the experimental part, corrosion stability of the titanium alloy Ti6Al4V in a simulated biological environment was examined. It was tried to determine the influence of chloride ions on the creation of a pasive film on the surface of the alloy. Through electrochemical testing, the tendency of the alloy for pitting was examined. The conclusion of the experiment is given in the end.
