BEASY will once again be attending the annual NACE Corrosion Conference, which this year is being held Phoenix from April 15th -19th 2018. We will be active in both the conference program and exhibit hall showing our corrosion modelling services and software.
We welcome you to come and visit our booth (No 1512) to find out more about the capabilities of BEASY simulation products, or how BEASY modelling services can provide the solutions you need. Alternatively to make an appointment to meet us at the conference, or to obtain further information, please contact us
Cathodic Protection
Comparison of Resistance to Cathode with Resistance to Ground in the Marine Environment
By John Baynham and Tim Froome
John and Tims paper at NACE 2018 focuses on the calculation of Anode resistance which is a fundamentally important quantity which is used in all CP system design work in the marine environment.
Established methods for calculation of anode resistance determine the resistance through the electrolyte between the anode surface and ground (or “remote earth”), and are based on analytical or approximate formulas. Such formulas are generally based on simplified anode geometry, such as long thin cylindrical bars, and may include effects of interference between multiple such bars grouped in fairly simple geometric patterns. Resistance to ground of real anode shapes may be very different from formula-based predictions even for single anodes, and computer-based simulation methods are now available to determine resistance to ground both readily and more accurately.

Predicting Aircraft Corrosion
Atmospheric Corrosion Measurements to Improve Understanding of Galvanic Corrosion of Aircraft
Matthew Merrill, Mark Kim, Fritz Friedersdorf from Luna Innovations and Thomas Curtin, Robert Adey from BEASY
Fritz will present the paper at NACE 2018. Atmospheric corrosion represents an annual multi-billion dollar cost burden for the aerospace and defense sectors. For many aircraft, particularly those operating in marine environments, up to ninety percent of corrosion is due to galvanic interactions at dissimilar metal couples. As new materials are introduced with the acquisition of more advanced aircraft, galvanic corrosion is likely to remain a concern. The ability to model galvanic corrosion accurately holds out promise of being able to not only predict the performance of new material combinations and guide material selection but also to predict corrosion damage to optimize maintenance.
A segmented, galvanic sensor is presented that enables the quantification of spatial distributions of galvanic current under thin film conditions that can be compared to model predictions for verification and to judge the suitability of immersion versus thin-film electrolyte data inputs.
