“You used the CM352,” he said.
She logged her report: “CM352 applied at 2% concentration. Chloride extraction rate: 94%. Long-term stability: Unknown. But for today—the blade sleeps.” cm352 corrosion inhibitor
Elara leaned back. The sword still looked like a wreck. But her handheld resistivity meter told a different story. The corrosion potential had shifted from -650 mV (active corrosion) to +120 mV (passive). The metal was, for the first time in two millennia, quiet .
The protocol was delicate. She couldn't immerse the sword; it would disintegrate. Instead, she used a capillary applicator. Touch by touch, she traced the inhibitor into the micro-fractures. And in the quiet of the museum, the
Elara knew what it was. CM352 was a strange hybrid: a corrosion inhibitor originally developed for reinforced concrete bridges, later adapted for archaeology. It wasn't just a sealant. It was a chelation agent with a specific electrochemical trick—it targeted free chlorides while bonding to the ferrous surface at a molecular level, forming a hydrophobic film only a few nanometers thick.
“The chlorides are eating it alive,” she muttered, reviewing the X-ray diffraction data. “If we use traditional alkaline washing, the metal will snap. If we do nothing, it powders within five years.” Chloride extraction rate: 94%
