Intercell bars for copper electrowining collect and transfer the DC current from one cell to the next adjacent cell in a series configuration. Equipotential intercell bars are made of a large continuous copper busbar conductor to receive the cathode currents from one cell, rebalance the potential of the electrodes and split the current to the next cell anodes. The potential balance by the bar itself...
Two of the major drivers for fretting corrosion are vibration and thermal cycling, with most previous studies focusing on experimental evaluation. It would be useful to develop and test a strategy for using computer modeling techniques to simulate the effects of vibration and thermal cycling induced fretting corrosion. Toward this end, finite element models are developed for a single blade/receptacle...
In order to accurately determine the remaining strength of pipelines with corroded defects, this paper studied the B31G Code and theoretical basis of the finite element analysis. Aiming at piping pressure of the same pipeline with corroded defect, we make direct calculation by B31G Code and Improved B31G ; according to the corroded defect size and piping internal pressure, mechanical model is set...
In this paper, the life prediction method of corroded aircraft aluminum alloy structure was proposed. The stress multiplication of aluminum alloy structure subjected to pitting corrosion damage was simulated by ANSYS software. Based upon the simulation results, the AFGROW software was used to carry out the crack growth analyses, the life cycles of corroded structure were estimated, and a very good...
In this paper, the corrosion fatigue crack propagation behavior of aluminum alloy specimens in corrosive solution has been investigated. Based upon the experimental results of corrosion fatigue growth, we proposed the stochastic processes method and the AFGROW software simulation method to predicate the numerical simulation of corrosion fatigue crack growth. The predicted crack growth curves agree...
With applied potential, the current distribution at the surface of a disk electrode is spatially nonuniform and time dependent. This distribution is important to control in applications that desire a uniform current density profile or minimal corrosion. We examine the current density profile of a capacitive disk electrode subjected to a voltage-step using finite element analysis software to solve...
