Abstract
Diplomová práce se zabývá návrhem, realizací a testováním struktur polymer - kov s různými typy 3D povrchových textur, které byly aplikovány na povrch polymerních dílů. Účelem této modifikace bylo umožnění efektivního "zakotvení" následně naneseného kovového povlaku pomocí galvanického pokovování. Pro zhotovení těchto dílů byly použity aditivní technologie stereolitografie (SLA) a maskované stereolitografie (MSLA). Dále byla pro porovnání zhotovena i tělesa aditivní technologií Multi Jet Fusion (MJF), a to bez povrchových textur. Připravené vzorky byly galvanicky pokoveny a poté podrobeny různým materiálovým zkouškám. Na základě vyhodnocení provedených zkoušek byly vybrány struktury polymer - kov s tzv. perspektivními texturami, které jsou v závěru práce vyhodnoceny s doporučením pro jejich využití v technické praxi.
The diploma thesis deals with the design, implementation and testing of polymer - metal structures with various types of 3D surface textures that were applied to the surface of polymer parts. The purpose of this modification was to enable effective "anchoring" of the subsequently applied metal coating through galvanic plating. Additive manufacturing technologies stereolithography (SLA) and masked stereolithography (MSLA) were used to make these parts. Furthermore, for comparison, parts were also produced using additive technology Multi Jet Fusion (MJF), without any surface textures. The prepared samples were electroplated and then subjected to various material tests. Based on the evaluation of the performed tests, polymere - metal structures with so-called perspective textures were selected, which are evaluated at the end of the work with a recommendation for their utilization in technical practise.
