Abstract (Croatian)

U teorijskome dijelu rada opisan je CVD postupak kemijskoga prevlačenja iz parne faze (engl. Chemical Vapour Deposition), njegove fizikalno-kemijske osnove, podjela, prednosti i nedostaci te primjena. Detaljno je opisan PACVD postupak s posebnim osvrtom na utjecaj energije iona (plazme), položaja i geometrije uzorka u reaktoru PACVD uređaja na kvalitetu prevlake. U eksperimentalnome dijelu, uz navedene parametre prevlačenja TiN prevlake i sastava osnovnog materijala (X38CrMoV5–3), prikazane su metode i detaljno analizirani rezultati ispitivanja kvalitete prionjivosti prevlake Rockwell C testom, debljine prevlake kalotestom i kemijskoga sastava TiN prevlake GDOES testom. Dobiveni rezultati ukazuju na značajan utjecaj načina šaržiranja obratka na kvalitetu prevlake i njenu debljinu.

Abstract

Theoretical part of this thesis describes the CVD process, its physical and chemical fundamentals, classification, advantages and disadvantages, application. A detailed description of the PACVD process follows, with special emphasis on the ions’ energy (plasma) impact and sample’s position and geometry in PACVD reactor on the quality of coating. In the experimental part of the thesis, next to TiN coating parameters and the base material’s (X38CrMoV5–3) composition, test methods, results and their mutual influence are analyzed in depth, and include coating adhesion quality via Rockwell C test, coating thickness via calotester and TiN coating’s chemical composition via GDOES test. The results point to a significant influence of the workpiece charging on the quality of the coating and its thickness.
