Thus, the rust is removed from the surface. It goes over the ablation threshold and the bond between the molecules and the metal breaks. When they fall over the rusty surface, the temperature of the molecules increases in no time. These can increase the temperature of the material instantly. The laser machines produce powerful laser beams. It is a must to adjust the power and speed of the laser machine accordingly to remove the layer of unwanted material. Therefore, if the energy is less, it cannot break the bond. The energy is used to break the bond of the rust from the surface of the iron. Otherwise, nothing will happen to the rust, no matter how many times you try. When the energy provided is greater than this threshold, the material is removed from the surface.įor instance, if you want to remove rust from the surface of iron, the laser beams should offer energy more than the Ablation Threshold. Basically, every material has a unique Ablation Threshold. This process is known as Laser Ablation, which refers to the removal of material from the surface of a solid by using powerful and intense laser beams. The powerful laser beams remove the rust particles at an exceptional speed without harming the metal underneath. Laser rust removal is a non-contact process of removing the layer of rust formed on the metal surface.
