Electrodeposition has a major advantage over other methods of thin film deposition. It allows deposition at atmospheric pressure and room temperature, requiring inexpensive equipment. However, there are several parameters which can influence an electroplated metal layer quality. The current density distribution is taken into consideration. The Hull cell is an electrodeposition tank with a ...

This project modeled an industrial chromium plating process for automotive components. The process was modeled via the COMSOL Multiphysics® Electrodeposition Module. The simulation examined the effect of solution conductivity, electrode spacing, and anode height utilizing a factorial design approach. A sensitivity analysis was used to study the effect of these variables on the thickness value at ...

The existing lithium ion battery model in COMSOL’s Multiphysics software is extended to include the thermal effects. The thermal behavior of a lithium ion battery is studied during the galvanostatic discharge process with and without a pulse. The existing lithium ion battery model in COMSOL 3.5a is extended by adding an energy balance and the temperature dependence of properties of ...

The Pulse Electrochemical Machining is especially suitable for the precise production of complex geometric contours with high precision and high surface quality demands in workpieces in series manufacturing. During this process, the negative structure of an electrode is copied to the workpiece without sub-surface damages. An adequate knowledge of the current density distribution and thus of the ...

In this paper, the cyclic voltammetry behavior of Ferrocyanide/Ferricyanide, which is commonly used for electrochemical DNA detection experiment, was studied in the commercial EQCM-D setup (Q-sense) using the COMSOL Multiphysics. The model was established in a 3D geometry of QCM liquid cell. The simulation shows depletion of concentration of ferrocyanice following applied electrode ...

Primary current distribution model for anodization of low-doped p-type silicon through a circular opening in frontside insulating mask is developed. The model is applied in two regimes of the process – pore formation and electropolishing – by definition of current density dependent functions of porosity and dissolution valence based on experimental results. As found also experimentally, ...

The silicon is mainly known under its single-crystal shape and polycrystalline. Since a few decades, a new type of morphology is developed: the porous silicon (p-Si). Meso-porous silicon (Mp-Si) is one of promising materials for future microelectronic chips multi-functionalization systems, and for micro-sensing devices. For thermal properties investigation many experimental systems were ...

This paper presents a 2D model of an intermediate temperature ammonia-fed SOFC (400 – 700 °C) based on the Temkin-Pyzhev model of ammonia decomposition. Phenomenological equations are implemented in COMSOL Multiphysics®. The Dusty Gas Model is used to model species transport in porous media, but a modification of Fick’s Law is used. Results show that intermediate temperatures can alleviate ...

Aqueous based copper electroplating seems the most reliable, flexible, cost effective method to create a copper layer on stainless steel coupler devices; this however, doesn’t imply a straightforward application, as subcomponents geometry is complex and tolerances are tight. At CERN, two existing copper electroplating baths were tested to evaluate the feasibility of plating three couplers ...
