Cracking down on corrosion with Hexigone Inhibitors

Good news! However, this invention dates seems to date back to 2015

Apparently, this new corrosion protection is already being marketed: 
Hexigone Inhibitors Ltd "In 2015, CEO and founder of Hexigone Inhibitors discovered a mechanism of protection that outperformed hexavalent chromate in laboratory tests, and the road to an innovate spin-out company began…  "

" ... The most common solution is to use corrosion inhibitors – additives and coatings that decrease the rate of corrosion. Until recently, hexavalent chromate was the most widely used. While effective, it’s extremely toxic, being both a carcinogen and a haemolytic capable of causing kidney and liver failure. ... "
