“…Laser cleaning, recognized for its high efficiency and environmentally friendly attributes, has been extensively researched as a novel cleaning technique. The adoption of continuous wave laser cleaning has become widespread due to its combination of affordability and robust performance [1][2][3]. Among them, the input power is the parameter with the most significant influence on the cleaning results.…”

“…Sun et al [4] found that the cleaning power is positively correlated with the cleaning depth. In the realm of numerical computation, stress alone does not fully explain the patterns of depth variation in cleaning [2,[5][6][7][8][9]; however, deformable meshing can mitigate this limitation. Continuous, direct laser irradiation produces heat buildup, and prolonged irradiation leads to surface roughness degradation and performance degradation [5].…”

A new multi-scenario, low-cost, high-efficiency, medium-assisted continuous laser cleaning of corrosion layers was developed. By comparing the roughness and cleaning depth of rust layers cleaned under conditions of liquid-assisted, solid-assisted, and mixed solid–liquid-assisted laser cleaning, simultaneously establishing a three-dimensional finite element model to study the variations during the cleaning process, and conducting a comparative analysis of the results of both, the cleaning mechanism is elucidated. The experimental results indicate that under conditions of water-assisted cleaning, the depth of rust layer increases initially and then decreases with varying water layer heights. The maximum cleaning depth is achieved at a water layer height of 0.1 mm, while the optimal surface roughness occurs at a water layer height of 0.2 mm, indicating a change in cleaning mechanism. The cleaning pattern with SiO2 activator assistance follows a similar trend to a water medium, reaching maximum cleaning depth at 0.1 mm height, with a slight improvement in surface roughness compared to water-assisted cleaning. Finally, solid–liquid mixing can achieve cleaning completion and improve surface roughness under conditions where water-assisted cleaning alone fails to reach a clean state. Therefore, the active agent can be used for laser cleaning to promote the cleaning process, and solid–liquid mixing to assist the laser cleaning can be a theoretical guide for the field of laser cleaning.
