The Battle Against Rust is Over
A billion EURO problem with a seamless solution
Rust and Rust creation
During oxidation, two oxide layers are produced,
at the surface Fe2O3 (thickness ≈ 20 nm) and in depth Fe3O4 (thickness ≈ 1000 nm or more).
The oxide layer exhibits a quite rough surface:
Its thickness is inhomogeneous (±100 nm around its mean value), and the lateral size of the grains is around 1 mm.
LASER CLEANING AND RUST REMOVAL
Laser rust removal, a type of laser cleaning, is an effective process for cleaning up metal parts. Using a fiber laser cleaning system, rust and other contaminants can be quickly and completely removed without damaging the metal underneath. Laser rust removal is a great alternative to manual and chemical cleaning methods since rust is removed with greater precision and lower recurring costs. It’s also a great way to reduce your environmental impact.
The removal of rust and oxide layers from metals is a laser cleaning application that is gaining very fast popularity due to the speed and flexibility that it offers. The process of removing rust from a metal appears to be the same as removing a painted layer, but there is a key difference. Rust and oxides are able to chemically corrode the bulk material, pitting and penetrating such that they are not just present on the surface. To fully remove high levels of rust, it is necessary to also engrave a thin layer of the substrate. The important takeaway is that the laser parameters needed to efficiently remove surface rust are not the same (in fact, practically opposite) as the parameters needed to best remove penetrating rust.
Rust Removal
Corrosion, rust, and oxides cause significant damage and drastically shorten the life and performance of parts and equipment.
Laser rust removal is faster and greener alternative to sandblasting and chemical removal methods since it completely removes rust and corrosion to the bare metal without altering the integrity of the metal itself. Our quick set-up and break-down time, makes laser rust removal the perfect solution for restoration and maintenance of parts and equipment.
Indicational Surface Cleaning capacity for each laser power
This are only indicational values for Reference, based on our own experience, each case must be checked specific and results depend on the layers and the underground
| Surface cleaning indicational capacity | layer thickness | 120W | 220W | 320 W | 540W |
| Oxide Layer or coated surface | m²/h | m²/h | m²/h | m²/h | m²/h |
| <25µm | 5,5 | 9 | 12 | 15 | |
| <50µm | 3 | 5 | 7 | 8,5 | |
| >50µm | 2 | 3,5 | 4,5 | 6 | |
| Rusty Scale | m²/h | m²/h | m²/h | m²/h | m²/h |
| <50µm | 3 | 6 | 8 | 12 | |
| <100µm | 2 | 3 | 4 | 6 | |
| >100µm | 1 | 1,5 | 1,9 | 2,8 |
