RUST AND COATING REMOVAL


Laser Rust Removal is a new alternative to Abrasive and Chemical techniques.  Not only can Laser be used to remove rust but it can also be used for different paints and coatings or grease and grime. The simplest application of laser ablation is to remove material from a solid surface in a controlled fashion. Also, laser energy can be selectively absorbed by coatings, particularly on metal, so CO2 or Nd:YAG pulsed lasers can be used to clean surfaces, remove paint or coating, or prepare surfaces for painting without damaging the underlying surface. High power lasers clean a large spot with a single pulse. Lower power lasers use many small pulses which may be scanned across an area. One of the advantages is that no solvents are used, therefore it is environmentally friendly and operators are not exposed to chemicals.It is relatively easy to automate. The running costs are lower than dry media or dry-ice blasting, although the capital investment costs are higher. The process is gentler than abrasive techniques, e.g. carbon fibers within a composite material are not damaged. Heating of the target is minimal. Laser ablation is also used in removing rust from iron objects easily
