Fabrication of metal-oxide thin-films and features on dissimilar materials via ion-assisted codeposition
… controlled by the flux ratio and ion energy. The codeposition on Si at higher total fluence is also shown to induce ripples in the Si surface in addition to the formation of nanodots, as is expected from normal incidence irradiation with the presence of small amounts of surface impurities. XPS has …

Nanocomposite coatings produced by electrodeposition from additive-free bath: the potential of the ultrasonic vibrations
… coatings and the optimization of the codeposition parameters. Two different nanopowder, i.e. silicon carbide and alumina, were added to a Watts type galvanic bath in order to produce the nanocomposites coatings and ultrasonic vibrations have been considered as an alternative to pitting …

Structure Evolution of Biaxially Aligned Thin Films Deposited by Sputtering
… grains in the thin film is obtained. With the codeposition of foreign elements, the structure evolution can strongly deviate from the proposed model because even a small amount of impurities will modify the atomistic processes. It is observed that the codeposition of even a tiny amount of …

An in-situ accelerator-based diagnostic for plasma-material interactions science in magnetic fusion devices
… presented, demonstrating the local erosion and codeposition of deuterium-saturated boron surface films. The finding confirms that deuterium codeposition with boron is insufficient to account for the net fuel retention in Alcator C-Mod.

Investigation on the Mechanism of Electrocodeposition and the Structure-Properties Correlation of Nickel Nanocomposites
… An advantageous production method is the electrocodeposition (ECD) process from metal plating baths containing dispersed nanoparticles. By using this technique, a broad range of substrate sizes and shapes can be coated cost-effectively. However, the prediction of the amount as well the …

Electrolytic remediation of chromated copper arsenate wastes
… analysis predicted that under the conditions of codeposition of all three metals, hydrogen and arsine would also be produced.

Synthesis, characterization, and thermal properties of ceramic-fullerene thin films
… dispersed fullerenes have been synthesized using codeposition processing, and the role that dispersed fullerenes play in the thermal behavior of co-deposited films has been characterized. The presence of C60 within the films has been confirmed using a new application of electron impact mass …

A study of the structure of codeposited PVD coatings
… from vertically opposed magnetrons and codeposition from coplanarmagnetrons, both using closed field magnetic arrays. Both methods arefundamentally the same. It is the orientation and manipulation of the substratesduring the deposition process which leads to either a multilayer …

Corrosion resistant chemical vapor deposited coatings for SiC and Si3N4
… from the single phase region predicted the codeposition of either Zr02 or Ti02 with ZrTi04. These results suggested that the chemical vapor deposition of ZrTi04 may be difficult from a process handling perspective. Additionally, the process is predicted to be very inefficient, leaving …

Electrochemical Synthesis and Characterisation of Multimetallic Nanostructured Electrocatalysts
… templating reactions) as well as sequential codeposition of noble metals (with or without SLRR templating reactions). Fundamental studies were conducted using thermodynamic and kinetic models, in situ electrochemical techniques and ex situ microscopic, spectroscopic, or spectrophotometric …

Electrodeposited metal matrix nanocomposites as thin films and high aspect ratio microstructures for MEMS
… how complexing agents affect the copper-alumina codeposition rate and establish the best operating conditions for useful nanocomposites for HARM’s. Recessed electrodes were prepared using X-ray lithography. Partial current density, current efficiency and deposited particle concentration were …

Mechanism of the NiCoFe ternary alloy deposition
Electrodeposited NiCoFe ternary alloys are of interest for their magnetic and thermophysical properties. The reaction rates and resulting composition and current efficiency are often determined empirically, due to a lack of understanding of the electrodeposition mechanism and coupled mass …
