Using Corrosion Djinn™ to Assess galvanic corrosion risk between dissimilar materials in design and sustainment
It is widely recognized that the galvanic potential difference (ΔE) between material couples is not a true indicator of corrosion rate, since the ΔE only indicates that corrosion is possible but it cannot predict the corrosion rate since it does not take into account the electrochemical kinetics. Corrosion current is the true reflection of kinetics which can be directly translated to corrosion rate. Indeed, at the recent ASETS Defense meeting (Denver Colorado, 22-Aug 2018), Victor Rodriguez-Santiago of NAVAIR PAX the current custodian of MIL-STD-889, outlined their plans for the revision of this standard by end of 2019, which will use corrosion current as a metric to quantify the galvanic corrosion risk.
Corrosion Djinn™ is a practical engineering web tool that anyone can learn to use in five minutes.
In less time that it takes to look up galvanic tables you can carry out an accurate galvanic corrosion risk analysis of material combinations. For the design or materials engineer it 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.
Djinn™ is a powerful tool due to the uniqueness of its underlying electrochemical database of modern materials, alloys, coatings and treatments. This database is continuously expanded to keep up with the fast pace of modern materials development. All data is gathered and validated in accordance with US Navy protocols.
This webinar is suitable for materials & process engineers, sustainment engineers, designers and managers. We will present the science behind galvanic corrosion risk assessment using the mixed potential theory and will demonstrate how Djinn™ can be quickly used to quantify galvanic corrosion risk and enable the user to assess alternative materials and coatings to mitigate corrosion.
Corrosion Djinn is easily accessible through any web-enabled device and attendees to the webinar will be provided with temporary access credentials in order to allow them to evaluate Djinn™ in their own time.
