Principle of laser rust removal
experiments show that when the metal surface has oxide, the plasma is produced on the metal surface.
the pulse width must be short enough to avoid the accumulation of heat that is destroyed by the treated surface.
absorption of large energy forms a rapidly expanding plasma (highly ionized unstable gas) that produces shock waves.
A) the beam emitted by the laser is absorbed by the contaminated layer on the surface to be processed.
The pulsed Nd:YAG laser cleaning process depends on the characteristics of the light pulses generated by the laser, based on the photophysical reactions caused by the interaction between the high-intensity beam, the short pulse laser, and the contamination layer.
