Abstract
A novel method for the removal and prevention of rust from corroded iron surfaces is disclosed. This is done by inducing reducing conditions at the interphase between the rusted surface and the attached aluminum surface. An iron coating provided by the reducing conditions surrounds the clean iron and creates a barrier against future rust. Our technology is an oxygen displacement technology which essentially removes rust from iron and iron based tools and structures. It is cost effective, non-invasive, environmentally friendly and can be mass produced.
