“…New materials comprising especially binary and ternary alloys and compounds as well as n ‐component materials can be fabricated in a rapid way or even in a one‐step experiment (). Well‐known techniques in this regard are represented by co‐sputtering and thermal co‐evaporation , which can both be used for preparation of thin film combinatorial material libraries. The most noticeable characteristic of a material library is the composition changing as a function of position on the sample.…”

Fabrication of cobalt-nickel material libraries was performed by electrodeposition in a modified 3D-printed Hull cell using sulfate-based electrolyte baths containing trisodium citrate or glycine as additives. A transition from anomalous to normal co-deposition behavior was observed for different overall applied current densities. Scanning electron microscopy (SEM) images showed needle-shaped crystallites on the sample obtained from citrate solution and a nodular surface morphology for the material library from glycine solution. Non-enzymatic glucose sensing was carried out by flow-type scanning droplet cell microscopy (FT-SDCM) to investigate the electrocatalytic activity for glucose oxidation.Cobalt-nickel material library fabricated by electrodeposition in the presence of trisodium citrate or glycine as additives using a modified 3D-printed Hull cell.

“…Combinatorial methods have recently become subject of increasing research interest due to their tremendous advantage of accelerated development of materials by means of relatively short time experiments. Apart from methods like co‐sputtering or co‐evaporation , electrodeposition represents a powerful fabrication method to prepare combinatorial material libraries, in which the composition of the deposited alloys change within the sample as a function of the position .…”

Cobalt-nickel material libraries were electrodeposited in two different types of modified Hull cells. Chloride and sulphate based electrolyte baths, the influence of the overall applied current density, cobalt concentration in the bath and addition of citrate as complexing agent were studied. The experiments suggested a higher cobalt content in the deposits for relatively low overall applied current densities and higher Co 2þ concentrations in the electrolyte bath. For the vast majority of the cobalt-nickel material libraries, a transition from anomalous to normal co-deposition behaviour was found as a result of the current density gradient establishing in the Hull cell during electroplating. Further examination was carried out by scanning electron microscopy (SEM), revealing a changing surface morphology within a material library depending on the cobalt content and the current density. X-ray diffraction (XRD) showed separate and mixed face-centred cubic (fcc) and hexagonal close-packed (hcp) crystallographic structures.Cobalt-nickel composition gradient obtained from two different Hull cell modifications including SEM micrographs of the material library deposited in the lying Hull cell.

“…The oxygen partial pressure during deposition was 0.6 Pa. More details about the reactive sputtering from sectioned cathodes were recently reported during the study of a Cu-Zn oxide material library. 27 The overall sputtering time was 190 min. Due to the diameter of the sectioned cathode, the Cu-Ni oxide compositional spread was deposited on two borosilicate glass substrates (Marienfeld microscope slides, 26 Â 76 mm 2 ).…”

A Cu-Ni sectioned cathode made up of two hemicycles of each of the metals was used for reactive co-sputtering of a thin film combinatorial library of Cu-Ni oxides covering a total compositional spread of 63 at.%. The thickness profiling of the library showed a nonuniform film thickness with a maximum region shifted toward the Cu side of the cathode. The presence of CuO, Cu 2 O, NiO, and metallic Cu-Ni alloys was identified during the scanning x-ray diffraction investigations along the compositional spread. A distinct structural zone was defined between Cu-14 at.% Ni and Cu-19 at.% Ni, where the scanning electron microscopy investigations showed a higher surface porosity combined with smaller grain sizes. This zone corresponds to the maximum film thickness region and correlates well with the position of the maximum work function of the Cu-Ni oxide films as mapped using a scanning Kelvin probe. During local corrosion studies focused on Cu dissolution, an improved corrosion resistance was identified in the Ni rich side of the compositional spread.
