Abstract

U radu su opisane osnove PACVD postupka, njegovi prednosti i nedostaci kao i nastanak tzv. efekta šuplje katode koji se može pojaviti prilikom prevlačenja uskih utora na strojnim dijelovima. Također je opisan utjecaj parametara PACVD postupka na svojstva dobivenih prevlaka, kao i utjecaj geometrije obradaka te njihove orijentacije u komori uređaja za prevlačenje. U eksperimentalnom je dijelu izvršeno ispitivanje koje se sastoji od prevlačenja uzoraka postavljenih u raznim konfiguracijama, prikaza i analize dobivenih vrijednosti kako bi se što bolje utvrdio utjecaj parametara prevlačenja i orijentacije strojnih dijelova te ispitala svojstva dobivenih prevlaka.

Abstract (english)

This thesis describes the basics of PACVD process, it's advanteges and disadvantages and so called hollow cathode effect that can appear whilst coating tight slots on machine parts. The influence of PACVD process parameters on coating performance is also described, as is the influence of substrate geometry and substrate orientation in the chamber of the PACVD machine. The experimental part of the thesis shows examination that consists of coating of the samples that are set in various configurations, representation and analysis of obtained data so the influence of process parameters and substrate orientation can be better determined and to examine the properties of the obtained coatings.
