Cyanide Free Alkaline Electrolyte and Electrochemical Process for Rust Removal from Plain Carbon Steel Components

Accessibility Controls

Implementing Organization

National Metallurgical Laboratory (NML)

Project Overview

Very fast electrochemical rust removal process (1-2 min) Alkaline cleaning process - No hydrogen embrittlement and the cleaned surface is passivated to prevent immediaterusting . The electrolyte is free from toxic elements like cyanides . Operated at room temperature . Very small components (screws) and big components can be cleaned . Ready for commercial use in plant scale

Benefits

This technology can be widely used in heavy industrial structures of plain carbon steel.
