Abstract

Tema ovog rada su biomedicinski metalni implantni materijali. Opisana su njihova glavna svojstva: biokompatibilnost, korozijska otpornost i otpornost na adhezijsko trošenje. Također su opisane pojedine vrste korozije: pukotinska, jamičasta, galvanska i intergranularna te je korozija opisana za različite vrste metalnih implantnih materijala. Implantni materijali su podijeljeni na: (a) nerazgradive (konvencionalne): nehrđajući čelik, legure na bazi kroma te titanij i njegove legure, i (b) razgradive: magnezij i njegove legure, cink i njegove legure te željezo i njegove legure. Objašnjeni su pojam i važnost sterilizacije materijala, sigurnost sterilizacije te je dana i opisana podjela sterilizacijskih metoda na glavne metode: sterilizacija zračenjem (gama zračenje, elektronski snop, rendgensko i ultraljubičasto zračenje), vlažna i suha toplinska sterilizacija, etilen oksid (EO) plinska sterilizacija, i alternativne sterilizacijske metode: Sterrad® (sterilizacija nisko-temperaturnom plazmom vodikova peroksida - LTHPGP sterilizacija), sterilizacija isparenim vodikovim peroksidom (VHP) te sterilizacija ozonom.

Abstract (english)

The main subject of this work are biomedical metal implants. Their main properties such as biocompatibility, corrosion resistivity and adhesion resistance have been described. Additionally, the different types of corrosion are presented: pitting, crevice, galvanic and intergranular corrosion as well as detailed description of corrosion for various types of biomedical materials. The metal implant materials are divided into (a) non-degradable (conventional): stainless steel, chromium alloys, titanium and its alloys, and (b) degradable: magnesium and its alloys, zinc and its alloys, and iron and its alloys. The concept and importance of materials' sterilization process and sterilization safety risks have also been studied. Furthermore, the classification of sterilization methods has been given: basic methods - radiation sterilization (gamma radiation, electron beam, x-ray and ultraviolet radiation), wet and dry thermal sterilization, ethylene oxide (EO) gas sterilization and alternative sterilization methods - Sterrad® (low temperature hydrogen peroxide gas plasma - LTHPGP sterilization), sterilization by evaporated hydrogen peroxide (VHP) and ozone sterilization.
