In the marine market, marine and offshore operators can corrosion is detected, they crack open to release a chemical that heals mi- croscopic cracks. They also ? uoresce in the presence of corrosion for easy visual inspection.
The self-healing smart beads detect and reveal corrosion forming on metal before it is visible to the naked eye.
When corrosion is present, the beads’ surfaces undergo a chemical reaction that causes them to ? uoresce (which can be detected with an ultraviolet [UV] light or Terahertz imaging), then break apart and release a heal- ing agent. The healing agent is cured by the corrosion by-products. The ? uorescence is a prompt indicator to maintainers that corrosion has initi- ated and provides them with the op- portunity to mitigate the underlying problem early on, while the healing agent immediately repairs the corro- sion damage and slows the corrosion process. The timely discovery and re- mediation of corrosion can result in signi? cant time and cost savings as well as improved structural reliability.
We asked Battelle Senior Battelle
Research Scientist Ram Lalgudi to ex- plain the technology, how it works and why. “The product contains a healing agent. The ion comes from corrosion.
It is a triggering mechanism for releas- ing the healing agent against the cor- rosion, said Lalgudi, continuing, “En- capsulation doesn’t increase thickness.
We are not adding mass to paint; the density of the paint is the same – we are not adding mass so it won’t in-
