Cleaning Rust of Iron using Pulsed CO2 Laser

Abstract

As general laser properties it’s unique, are used in a wide variety of applications in all walks of life. The common problem to metal industrial is rust. The rust is a layer coated surfaces of metallic object which decreases the performance of metal in its applications. In the thesis work,CO2 laser used to remove rust from the surfaces of ironic objects by focusing a laser beam on the surface of two samples (flat and carved). The output power of the laser was selected in such a way that the beam cannot melt or evaporate the surface of the metal, and the energy of the pulse was 0.3 J, while the pulse frequency was approximately 400 Hz. The experimental results indicate that the beam of laser causes evaporation of rust, and better cleaning was obtained in booth flat and curved surface. Laser beam can be used to clean regions that are difficult to clean by common method, saved time and exertion.
