Abstract

Teorijski se dio rada sastoji od četiri poglavlja u kojima su opisana svojstva i primjena titanijevih legura nakon kojih slijedi opis aditivnih tehnologija i svojstva tako dobivenih titanijevih legura s posebnom pozornošću na Ti6Al4V. Sljedeći dio posvećen je postupcima prevlačenja s fokusom na PACVD postupak i TiN prevlake. Završno poglavlje teorijskog dijela opisuje metode karakterizacije kojima je opisano stanje površine u eksperimentalnom dijelu.
U eksperimentalnom dijelu rada ispitan je kemijski sastav EDS metodom, svojstva hrapavosti površine, prionjivosti i debljine prevlake te nanotvrdoća TiN prevlake nanesene PACVD postupkom. Svojstva prevlake PACVD TiN na aditivno i konvencionalno proizvedenoj titanijevoj leguri Ti6Al4V sličnih su vrijednosti i potvrđuju mogućnost uspješnog prevlačenja aditivno proizvedene legure.

Abstract (english)

The theoretical part of this thesis consists of four chapters which examine the properties and application of titanium alloys followed by a description of additive manufacturing of titanium alloys with focus on titanium alloy Ti6Al4V. The next chapter describes processes of coating the materials with focus on PACVD process and TiN coatings. The last chapter is about surface characterization methods which were used to describe a surface condition in experimental part.
In the experimental part chemical composition by EDS method, surface roughness, nanohardness, adhesion and thickness of TiN coating applied by PACVD have been examined. The properties of PACVD TiN coating on conventionally and additively manufactured Ti6Al4V alloy have similar values and confirm a possibility of successful coating of additive manufactured alloy.
