L The cellular automata (CA) methodology is applied to the case of intergranular corrosion. Appropriate CA rules are generated which can reproduce and predict the advance of a corrosion front. The proposed model shows qualitative and quantitative agreement with experimental intergranular corrosion data obtained from an aluminium AA2024 alloy in chloride solutions. 2011 Elsevier Ltd.

Influence of Silicon, Carbon and Phosphorus on Intergranular Corrosion of High Purity Austenitic Stainless Steels Under Transpassive Conditions
Precipitate-free Fe-Cr-Ni f.c.c. alloys exhibit strong intergranular corrosion in acid solutions at electrochemical potentials from the transpassivity range. Segregation of impurity atoms to grain boundaries is generally considered to be responsible for this specific kind of localized damage. A study of the influence of silicon, phosphon~s and carbon on the intergranular transpassive corrosion ...

In this paper we proposed a Cellular Automaton based local algorithm to solve the autonomously sensor gathering problem in Mobile Wireless Sensor Networks (MWSN). In this problem initially the connected mobile sensors deployed in the network and goal is gather all sensors into one location. The sensors decide to move only based on their local information. Cellular Automaton (CA) as dynamical sy...
متن کاملCellular Automata Approach to Corrosion and Passivity Phenomena
Our research on employing the cellular automata methodology to corrosion and passivation phenomena is reviewed. Examples of a peculiar pit development are found and presented. The diffusion rate in the corroding medium is argued and shown in the simulation results to affect mainly the characteristic length scale for the corrosion process. New data for the pitting corrosion development on a plan...
