Corrosion Djinn
Computational Corrosion Analysis Built With Designers & Material Engineers In Mind
What is Corrosion Djinn?
Corrosion Djinn® (Djinn) is a platform for managing electrochemical data and quantifying galvanic corrosion risk in compliance with MIL-STD-889D.
As predictive corrosion risk analysis becomes more prevalent in engineering and design organizations it is imperative that the essential electrochemical materials & coatings data is managed and made available at the point of need.
Wide Range of Material Data
We have a wide range of materials available in Corrosion Djinn with over 200 materials widely used across Aerospace, Automotive and Marine applications.
If you’re data isn’t present in the Corrosion Djinn database we can gather the required electrochemical data.
Data Suitable For Your Environment
Polarization curves are unique to each material in each environment. This includes any treatments to the materials and any changes to the alloys.
We have over 200 polarization curves in our database relevant to the MIL-STD-889D (artificial seawater) environment and in a 3.5% NaCl environment.
If you need data in a specific environment we can help gather this data.
CAD Agnostic
Corrosion Djinn provides a 1D galvanic corrosion risk analysis that does not rely on CAD or a 3D Mesh.
It is the perfect tool for performing an initial check to easily see the galvanic compatibility of materials.
Corrosion Djinn functionality can be extended by providing material area ratios to provide a more accurate analysis.
Additionally, the Corrosion Djinn database can be used in Simcenter STAR-CCM+ for a higher fidelity result.
How does Corrosion Djinn work?
It is widely recognized that the galvanic potential difference between material couples is not really a true indicator of corrosion rate, since the potential difference does not depend on the kinetics. Indeed, MIL-STD-889D states that the maximum corrosion current is identified by the crossing point of the material polarization curves, which is what Djinn does by accessing a database of consistent, accurate, modern polarization curves. All of the polarization data has been acquired by following a measurement protocol developed and published by NAVAIR, the custodians of MIL-STD-889. Consequently, the Djinn Platform can provide a more accurate insight into possible corrosion rate and consequent risk.
The methodology used in this software is based on the mixed potential theory of electrochemistry that was first formulated 70 years ago and has been validated and used by electrochemists ever since. It is based on the principle that the common potential reached by two dissimilar materials in electrical contact, and the galvanic current between them is determined by the crossing points of their polarization curves.
Interactive MIL-STD-889D
The Corrosion Djinn platform includes an interactive version of MIL-STD-889D for free.
You can access this on Corrosion Djinn, this interactive tool is designed to simplify using the MIL-STD-889D protocol without having to rely on reading along mileage charts which can easily lead to mistakes.
Material Data Management
For customers with their own material data this can be added into the SaaS platform for your use only, alternatively we have Corrosion Djinn Standalone for hosting your own data on-premise.
Any material and electrochemical data inside of Corrosion Djinn SaaS & Standalone can be exported to be used directly inside of NX & Simcenter Star-CCM+.
Deployment Options
Corrosion Djinn has additional deployment options in addition to the Software-as-a-Service option.
For customers who would prefer an on-premise solution we have Corrosion Djinn Standalone which has the exact same functionality.
Evaluation
The Corrosion Djinn® software can be accessed and evaluated for free at corrosiondjinn.com.
You can test the Galvanic Corrosion Analysis process for a few selected materials in the MIL-STD-889D environment, including the new anode to cathode area ratio features. You will also be able to see a list of materials that are available in Corrosion Djinn under the Substrates & Coatings menus.
