Abstract
This paper utilizes a nanosecond pulse fiber laser to conduct rubber removal experiments on rubber laminated metal valves. The influence on surface roughness, metallographic structure and hardness of samples before and after different laser cleaning conditions are analyzed. Experimental results show that the laser has no significant effect on the substrate situation of the rubber laminated valves when it is immersed in water or sprayed with water. Through thermal simulation, the surface temperature when using wet-type laser cleaning is lower than that of using dry-type laser cleaning, and there is no significant effect on the substrate. Therefore, wet-type laser cleaning is appropriate for rubber laminated metal valves.
