MIL-STD-889 for Dissimilar Materials is changing – are you ready?
At the last 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 MIL-STD-889 Dissimilar Materials standard by the end of 2019. This revised standard will replace galvanic potential with corrosion current as a metric to quantify the galvanic corrosion risk.
It is widely recognized that the galvanic potential difference (ΔE) between material couples is not a true indicator of corrosion rate. It only suggests 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 outcome of kinetics which can be directly translated to corrosion rate.
This webinar will show examples of where MIL-STD-889 fails in the field and why it is being revised.
The planned revisions will in fact demand a new approach and access to significantly different data. We will introduce the science of the mixed potential model and demonstrate how this is leveraged by intersecting the polarization curves of different materials to directly calculate the corrosion current and hence quantify the corrosion rate. Compliance with the new MIL-STD-889 can be greatly accelerated with the use of our easy to use Corrosion Djinn™ software tool and associated electrochemical database which we will also demonstrate.
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.
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 webinar attendees will be provided with temporary access credentials in order to allow them to evaluate Djinn™ in their own time.
The current scheduled dates and times for the webinar are February 26th at 10am and 4pm EST.
