Processing Ion Beam Mixed Nickel/Polyimide Thin Films
We have established a method of fabrication for Nickel/Polyimide ion beam-mixed films using thermal evaporation. We then used the low-temperature characterization system in the Materials Physics Testing lab at SMSU to measure the resistance of each film as a function of temperature. These methods …

Investigation of electroless nickel undercoat for duplex nickel chromium electrodeposition onto aluminium and its alloys
The study investigates the deposition of a multilayer coating onto two aluminium alloys: Al 1050 and Al 6061. Of particular interest has been the treatment of the surface of both these samples for deposition of metallic coatings through a zincate based immersion process. The zinc immersion layer …

Fabrication and robustness testing of superhydrophobic nanostructured surfaces for enhanced jumping condensation
… titanium, stainless steel, and electroplated nickel. Hydrophobic coatings tested on these surfaces included stearic acid and two polymer coatings: P2i (40nm) and Semblant. Observed failure mechanisms were coating degradation and poor nanostructure adhesion. Nanostrucure adhesion issues were …

Integrated Catalytic Fabrication Approaches for Graphene-Based Electronic Devices
… become embedded below the Al$_2$O$_3$ ALD layer during the encapsulation process, which prevents the passivation of the graphene surface and the restoration of its intrinsic electronic properties. The transfer-free catalytic graphene growth, directly at the interface between the metal …

Ultrafast Dynamics and Interactions During Growth at Surfaces
… adatoms causing a reconstruction of the first nickel layer. Even so, the islands have a clear impact on the diffusion signature, demonstrating that they are not static and thus that a dynamic equilibrium is established between the clusters and their mobile precursors. We have also studied …

Automatizace procesu svařování HSS v prostředí JE
Bakalářská práce srovnává ruční a mechanizovaný způsob svařování při výrobě heterogenního svarového spoje. Vzorky byly svařeny z austenitických a feriticko-perlitických základních materiálů za použití stejného typu vysoko-legovaného přídavného materiálu. Geometrie spoje pro oba způsoby shodná. Byly …
