“…The intensity of the laser within the polyacrylate paint follows the Lambert law, which can be described as [32]: Where h is the penetration depth and a is constant that a≈10 6 m −1 for the paint [8,33]. Therefore, the laser only penetrates a few microns in the paint.…”

Laser stripping paint was studied with a pulsed laser in our work, which focuses on the effect of the process parameters, and on the understanding of the mechanism of this type of technology. Regarding the characterization of the stripping surface, surface morphology and surface roughness had been determined by a three-dimensional profilometer. The orthogonal optimization experiment had been carried out to optimize the process parameters. Combining experiments with simulation calculation, the laser stripping paint mechanisms were thoroughly investigated. Stripping paint with a pulsed laser is dominated by the thermal combustion effect, thermal stress and thermal vibration effect, laser plasma shock effect.

Paint layer was stripped from the 2024 aluminium alloy aircraft skin by either 1000 grit sandpaper or laser with 150 ps pulse width while the laser paint stripping (LPS) process was recorded by a high-speed camera. The surface and cross-section morphologies, chemical compositions and chemical valences of obtained the paint stripping samples were also characterise. The corrosion resistance was determined by the Potentiodynamic Polarization Curve (PPC). On mechanical paint stripping (MPS) samples, a large amount of scratches remained. Surface roughness increased and the oxide film was removed completely. The trace of the laser scan was observable on the surface of LPS samples. Recrystallisation occurred on the LPS surface and eventually formed arrayed micro and sub-micro structures. The oxide film is mainly composed of Al2O3 with a thickness about 2.10 µm. The corrosion current density of mechanical and LPS samples are 3.66 ×10−2 mA·cm−2 and 6.66×10−5 mA·cm−2, respectively. Comparing to MPS which removed all the oxide film and damaged the substrate metal, LPS only damaged the oxide film mildly without damaging metal substrate. The remaining oxide film contributes to a higher corrosion resistance of the LPS sample.
