Corrdesa's CTO, Dr. Keith Legg presents at SUR/FIN 2021
Dr. Keith Legg will present, Blum Lecture: Modeling and Simulation for the Finishing Industry, at SUR/FIN 2021 on Tuesday, November 2nd at 14:15 Eastern USA.
Modeling and Simulation (M&S) has become an integral part of modern design and manufacturing. Today, no major product is designed without the use of M7S. In the past we put scale models of aircraft and cars in wind tunnels, and used smoke to track the airflow. Today, we use computational fluid dynamics (CFD) to understand exactly how the air flows under all possible conditions, calculating drag and lift in air vehicles or drag and road holding in road vehicles. We use stress analysis to ensure every part of the vehicle is robust and structurally sound, and heat flow analysis to design its engine, cooling system and passenger space.
For a long time the plating and surface finishing industry has been able to get by without complex (M&S), because the processes and equipment for surface finishing, and requirements for surface finishes were not overly complex. But in the past years the complexity has increased significantly due to environmental regulations, cost and performance, and robotics. Simple electroplates such as Zn and Cd are being replaced by ZnNi, hard chrome is giving way to trivalent chrome, alternative electroplates and thermal sprays, while chromate conversion is being replaced by non-hexavalent materials that are often more sensitive to process conditions and therefore harder to use. Even paints are changing to reduce volatile organics and chromates, and painting is becoming automated, while soon a host of minor constituents of paints and adhesives will suddenly find themselves orphaned by REACH regulations and have to be replace.
This talk will examine what other industries are doing, see what is most pertinent to Surface Finishing, discuss capabilities and limitations, possibilities and caveats, and hopefully provide some guidance on how the Surface Finishing industry can quickly and profitably adopt the most useful M&S for the 21st century.
Upcoming MIL-STD-889D Webinars
In the upcoming webinars we will present and discuss the challenges in implementing a consistent corrosion analysis capability across enterprises. We will introduce a workflow that incorporates a quick galvanic corrosion calculation using the Corrosion Djinn® software, developed from our DoD work and fully compliant with MIL-STD-889D.
Additionally we will show how full 3-dimensional, deeper dive corrosion analyses can be conducted using the Siemens Teamcenter® and multi-physics software CCM+ combined with the Corrdesa electrochemical database to predict corrosion rate maps over 3D CAD components. This process will be demonstrated with examples of computational corrosion analysis on F/A-18 components.

New Paradigm Galvanic Corrosion Spec MIL-STD-889D to launch in 2021
Briefings presented by NAVAIR at ASETSDefense 2020, MIL-STD-889D Overview by Victor Rodriguez-Santiago , show how the DoD has been changing the primary military specification for galvanic corrosion control, getting rid of galvanic tables and replacing them with the calculated galvanic current between each pair of materials.
The new MIL-STD-889D specification contains “Mileage Charts” showing the calculated galvanic current at the interface between different metals and between different coatings.
Corrdesa’s Corrosion Djinn® already meets MIL-STD-889D to give corrosion rates between any two materials/coatings. Djinn allows you to quickly determine the galvanic current between any two materials, including composites, metal filled primers, and coatings.

Dr. Alan Rose and Dr. Keith Legg speak at SERDP-ESTCP Symposium
The Symposium is an annual event showcasing technologies to meet environmental regulations such as REACH and OSHA.
Dr. Keith Legg, CTO of Corrdesa, ran the “REACH Short Course – Practical Effects and Approaches” and discussed “ Accelerated Test and Evaluation for Materials Qualification“, a rapid approach for qualifying non-chromate alternatives, etc. In addition, Dr. Legg ran an informal side meeting on the deposition of LHE ZnNi, which is displacing Cd for corrosion protection of aircraft landing gear, actuators, etc.
Dr. Alan Rose, CEO of Corrdesa, presented ” ZnNi and Tagnite Performance on Complex Parts -Corrosion Risk Mapping “, a briefing on modeling of LHE ZnNi deposition. Dr. Rose demonstrated the importance of computationally designed tooling for electroplating, and the effect of current density variations on the properties of the coating. In particular, Dr. Rose showed that ZnNi is not a sacrificial coating in low current density areas – often exactly those areas where sacrificial corrosion protection is most needed.
New Webinar Available! Learn how to comply with the NEW standards for corrosion protection.
In July, Corrdesa’s Dr. Alan Rose joined Knovel for the webinar, Complying with the New Standard of Corrosion Protection, to talk about significant changes to the MIL-STD-889 covering dissimilar metals and galvanic corrosion. In this webinar, Dr. Rose explains the latest findings which show that galvanic corrosion is best determined by galvanic current between materials, not by potential difference. He also reviewed key changes in the dissimilar metals and galvanic corrosion standard (MIL-STD-889C), currently in development. Learn how to comply with the new standards of corrosion protection. You can access the Webinar at the link below.
We are pleased to welcome Dr. Vinod Upadhyay to our team as a scientist!

Dr Keith Legg will be at SUR/FIN 2019
Corrdesa’s CTO Keith Legg will be presenting twice at SUR/FIN 2019 in Rosemont, Illinois! The first presentation will be “On-Aircraft Non-Drip Selective Anodizing” at 12pm on June 4th and the second will be “Updates on Galvanic Corrosion MIL-STD-889 and New Corrosion Test Development” also on June 4th and both will be held in Meeting Room 4.
Introducing Dalistick Non-drip selective anodizing for on-aircraft repair
Corrdesa is the US distributor for Dalic, the French company that invented the non-drip plating and anodizing technology, which uses a closed-loop system to selectively anodize or electroplate, even overhead. The nondrip technology uses airflow to hold the electrolyte in the plating tool and on the surface, avoiding the need for seals or dams. Find out more about the tool here or contact us!
At MRO Americas we’re showing how the latest non-drip brush plating technology ensures low waste, low emissions but the highest product quality. The machines can be used on-aircraft in small spaces and overhead areas, without chemicals dripping onto equipment, operators, or the floor.
We're ready for MRO Americas in Atlanta, GA
Corrdesa attended NACE 2019
Whilst in Nashville at Corrosion 2019, Corrdesa gave many demonstrations of Corrosion Djinn and provided new connections with free trials to try back in their own environment. It has never been easier to explore possible coating protection options for product designs. We are looking forward to receiving their feedback soon.
Attending NACE Corrosion 2019 was a great experience and gave us the opportunity to demonstrate our quick, accurate galvanic corrosion prediction tool – Corrosion DjinnTM. Our presentations were well attended and can be found on our resources page.
We are all set up for NACE Corrosion 2019 in Nashville, Tennessee.
Between March 25th and March 28th, come along to booth 2648 for a demonstration of Corrosion Djinn and receive a free trial!
Galvanic Corrosion Protection: Those Old Galvanic Potential Tables Are Finally Being Replaced
The galvanic potential tables people have been using for years often give the wrong answer. Now the U.S. Navy is taking a new approach and updating MIL-STD-889, the galvanic corrosion standard, replacing galvanic charts and tables with corrosion rate calculations. What does this mean for industry?
Corrdesa will be presenting: Using simulation to understand the difference between corrosion in atmospheric environments and chamber tests at NACE Corrosion 2019 on March 27th in Nashville

Alan Rose will be presenting "Corrosion Prediction and Testing for Aerospace and Defense" alongside representatives from Southwest Research, NAVAIR and Boeing at NACE Corrosion 2019
Alan will be presenting “Corrosion Prediction and Testing for Aerospace and Defense” on March 26 at NACE 2019 which is taking place in Nashville, Tennessee. Find out more here. Corrdesa will also have a booth at NACE so come and see us in Booth #2648!
The Simcenter conference was very interesting, providing a great opportunity to learn more about the present software tools and also the trends in future development. One key takeaway for Corrdesa was the presentation on ‘Design Manager’ – this is a very powerful tool allowing easy setup of many simulations to more thoroughly explore the design space. So now we have changed out engineering workflow to think in more of a stochastic framework of many simulations and ranges of parameters instead of deterministic simulations of one scenario after the other. This approach really leverages the power of our computing cluster and provides much more optimum solutions to our clients.
Alan’s corrosion simulation presentation was very well received with many questions and follow-up meetings. Much of the Siemens Simcenter community were unaware of the existence of the electrochemical modules within CCM+ and in particular the advances made in corrosion prediction.
The presentation is available here showing how the ‘1D’ approach of Corrdesa Corrosion Djinn can be leveraged to assess corrosion risks in materials selection and then further refinement made in more complex designs with the use of CCM+ employing the Corrdesa electrochemical database
We would like to welcome Dr Julio Mendez to our team as a CFD engineer!
