20.500.12556/RUL-167060 Analiza vpliva tehnologije odrezavanja ZnO keramike z definirano geometrijo na končno kakovost izdelkov lnfluental analysis of machining technology with defined geometry on the final ZnO ceramic product quality Doktorsko delo obravnava problematiko obdelovalnosti ZnO keramike iz vidika zagotavljanja ustrezne kakovosti končnega izdelka, visokonapetostnega varistorja. Ključna identificirana karakteristika za pravilno delovanje je stanje roba diska in adhezijska napetost naknadno nanešenega aluminijastega sloja. Delo vsebuje analizo vpliva tehnologije odrezavanja za doseganje željenih karakteristik ZnO varistorskega diska iz vidika doseganja primernega razreda krušenja keramike ter s pomočjo analitičnega modela teksturiranja površine in eksperimentalno razvitega sistema za ultrazvočno oscilacijo rezalnega roba tudi realno doseganje namensko teksturiranih površin. S tem je moč doseči ustrezno adhezijsko napetost aluminijastega sloja. This PhD thesis addresses the issue of the machinability of ZnO ceramics from the point of view of ensuring the appropriate quality of the final product, the high-voltage varistor. The key identified characteristic for proper performance is the condition of the disc edge and the adhesion strength of the subsequently deposited aluminium layer. The work includes an analysis of the influence of the cutting technology for achieving the desired characteristics of a ZnO varistor disc in terms of achieving a ductile machining regime and also the realistic achievement of purposefully textured surfaces by means of an analytical surface texturing model and an experimentally developed ultrasonic cutting edge oscillation system. This allows to achieve the appropriate adhesion strength of the aluminium layer. odrezavanje keramika ultrazvočna oscilacija orodja obdelovalnost kakovost hladno napraševanje cutting ceramics ultrasonic cutting edge oscillation machinability quality cold sputtering true false false [J.
