Mending the unmendable: A new method for restoring fractured metals

https://techxplore.com/news/2023-04-unmendable-method-fractured-metals.html

"electrochemical healing" to repair fractured metals in various metallic materials, including steel, aluminum alloys, and complex 3D printed structures, under room-temperature conditions... turned ions into solid metal atoms, atoms grew on surface healed fracture... applied protective polymer coating... low-carbon steel, 2 unweldable aluminum alloys... can recover 100% strength... repair 3D... full tensile strength restoration... autonomous repair and reducing costs with alternative electrodeposited metals"
