What is Djinn?

Easy to use

Corrosion Djinn™ is an intuitive engineering web tool that anyone can learn to use in five minutes.

Quick

In less time than it takes to consult galvanic tables you can already execute accurate galvanic corrosion risk analyses of many material combinations

Dependable

All data is gathered and validated in accordance with US Navy protocols and is continuously expanded to keep up with the fast pace of modern materials development

Powerful

Corrosion Djinn™ is a powerful tool due to the uniqueness of its underlying electrochemical database of modern materials, alloys, coatings and treatments.

Great value

Save on expensive design modifications and repairs by ensuring choice of compatible materials from the outset.

For the design or materials engineer Corrosion Djinn accurately predicts corrosion rate and gives a color-coded go/no-go analysis of risk. The visual results are easy to read and interpret providing actionable information to eliminate bad choices and choose optimum alternatives.

How does Djinn work?

Corrosion Djinn is easily accessible through any web-enabled device. Problems can be evaluated and solved in any location from the design office, board room or flight line.

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-889C states that the maximum corrosion current is identified by the crossing point of the material polarization curves, which is what Corrosion 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. More details can be found in the USER Manual.
