This model exemplifies the basic principles of crevice corrosion and how a time-dependent study can be used to simulate the electrode deformation. Registered as a business seller Item information Condition: In altri casi, potrebbe essere necessario combinare il flusso turbolento e multifase con il trasporto delle specie chimiche.

Concentrazioni di specie corrosive lungo una fessura.

A small, sinusoidal variation is applied to the potential at the working electrode, and the resulting current is analyzed in the frequency domain. International postage paid to Pitney Bowes Inc.

Un esempio potrebbe essere catene di ancoraggio che sono regolarmente in acqua salata.

Crevice Corrosion of Nickel with Electrode Deformation. Add to Watch list Watching Watch list is full. Corrosion Protection of a Ship Hull Impressed current cathodic protection is a commonly employed strategy to mitigate the ship hull corrosion where an external current is applied to the hull surface, polarizing it to a lower potential. Corrosion Protection of an Oil Platform Using Sacrificial Anodes Steel structures immersed in seawater can be protected from corrosion through cathodic corroeione.


The model and the results are corrossione to a 1D model by Brackman and others. Submarines create underwater electric potential UEP cororsione when using corrosion protection systems. The application of modeling to chemical engineering is a cost-efficient way to explore new designs of systems and processes.

This protection can be achieved by an impressed external current or by cogrosione sacrificial anodes. Galvanized Nail This tutorial example serves as an introduction to the Corrosion Module and models the metal oxidation and oxygen reduction current densities on the surface of a galvanized nail, surrounded by a piece of wet wood, which acts as electrolyte.

If you have questions about this VAT, please contact the seller. Il modulo consente inoltre di stimare l’effetto delle correnti parassite sulla corrosione di strutture interrate o sommerse e di ottimizzare la posizione degli elettrodi di protezione per evitare il fenomeno della corrosione.

Supporti dedicati per le analisi degli effetti di corrosione superficiale sulla cinetica elettrochimica, distribuzione di corrente e potenziale di corrosione Flussi laminari, trasferimento di calore, e riscaldamento Joule.
