Nanos aluminija na ZnO keramično površino z metodo hladnega napraševanja

Tuta, Janko (author), Pušavec, Franci (mentor)

Tehnologija hladnega napraševanja je precej nepoznana ampak hitro razvijajoča tehnologija za nanos prevlek. Cilj naloge je združitev tehnologije hladnega napraševanja z računalniško vodenim numeričnim krmiljenjem, za namene napraševanja aluminijevega prahu na ZnO keramično površino. Tekom eksperimentalne faze je bil didaktični CNC stroj Emco concept mill 105 integriran z prenosnim hladnim napraševalnikom Dymet. Z omenjenim sistemom je bila na ZnO keramično ploščico nanešena aluminijeva prevleka. Analiza rezultatov je zajemala analizo debelin nanosa in trdnosti vezi nanosa, ta se je preverila z preskušanjem oprijema z odtrganjem filma po standardu ISO 4624. Rezultati so potrdili ustreznost tehnologije hladnega napraševanja za nanos aluminija na ZnO keramične površine.

• Title: Deposition of aluminium on a ZnO ceramic surface by cold spraying

Abstract

Cold spraying technology is relatively unknown but fast developing coating technology. The aim of this work is to combine cold spraying technology with computer numerical control for the purpose of spraying aluminium powder on ZnO ceramic surfaces. During the experimental phase, Emco concept mill 105 didactic CNC machine was integrated with a Dymet portable cold spray machine. With this system, aluminium coating was applied to a ZnO ceramic tile. The analysis of results consisted of coating thickness analysis and verification of coating bond strength by pull off test according to ISO 4624 standard. The results confirmed the suitability of the cold spray technology for the deposition of aluminium on ZnO ceramic surfaces.
