Self-Healing Coatings to Mitigate Corrosion and Impact Damage
Project ID: 1623
Principal Investigator: Christine Daniels
Research Topic: Repair and Maintenance
Funded Fiscal Years:
2016
Keywords: None
Research Question
Can a self-healing coating additive developed by Battelle be used in conjunction with Reclamation coatings to
mitigate corrosion and low impact damage?
Need and Benefit
A main goal of BOR is the delivery of water and power. Dams, pipelines, and canals are among the structures built
with concrete that are used for this purpose. In order to mitigate corrosion associated with metals and concrete a
number of coatings are used. But coatings are not always fail safe. They can experience low impact damage as
well as corrosive damage in defective areas. This causes maintenance problems and expenses, and can cause loss
of revenues related to water delivery and power generation.
Self-healing oligomer filled microcapsule coating additives may provide additional options in the protection of
Reclamation's coated infrastructure. Although this technology has been around for a close to a decade and has
been published in many academic journals there have been some issues associated with the catalyst activated
version of this technology. Battelle has come up with a non-catalyst version that appears promising. In support of
a project funded by Office of Naval Research, Battelle demonstrated this technology on several Humvee doors as
well as on coupons that were mounted on the back bumper of two Humvees located at Camp Lejeune, NC. They
also did beachfront exposure testing at their Florida Materials Research Facility in Daytona Beach, Fl. Results
showed the coatings with Smart Corrosion Beads demonstrated improved performance in these tests.
This literature and analysis study will help determine if this technology is another viable solution to further
enhance Reclamation's infrastructure maintenance and reliability management. If so, it will be useful all
throughout Reclamation.
