Non-Destructive Rust Removal

Definition - What does Non-Destructive Rust Removal mean?

Non-destructive rust removal is a technique in which iron oxide is removed without harming the material being treated (i.e., there is no loss to the material on which this non-destructive technique is performed).

This technique is performed with the aid of a electrolysis, which removes iron oxide (rust) by passing a small electric current, generated either from a battery or a battery charger, through the rusted metal surface to initiate an exchange of ions in the electrolytic solution. The direct current (DC) is used to drive a non-spontaneous chemical reaction. This process is performed by keeping the rusted metal submerged in an electrolyte solution, which removes the rust instantly without damaging the metal's surface.

Corrosionpedia explains Non-Destructive Rust Removal

Non-destructive rust removal is a harmless technique that does not cause any further loss of the material being treated.

Electrolysis involves the passage of a direct current through an ionic substance that is either molten or dissolved in a suitable solvent, which results in a chemical reaction at the electrodes and material separation.

Electrolysis is considered a highly important commercial process to separate unwanted elements or ions from naturally occurring sources, such as ores, using an electrolytic cell.
