As shown in the figure, the absorption coefficients of various metals change with wavelength. At λ=916nm-1200nm, most metals have higher absorption coefficients in this band, and organic matter has relatively strong laser absorption in this band. Because of this, in terms of absorption rate, combining the comparative advantages of various aspects, fiber lasers have demonstrated unique advantages in all aspects. The organic pollution layer absorbs the laser strongly, and the temperature of the organic pollution layer quickly rises to the evaporation point to vaporize, thereby achieving the purpose of removing the pollution layer without damaging the substrate. Then determine the energy threshold of laser cleaning, the energy threshold of laser cleaning will determine the effect of laser cleaning. Selecting the appropriate laser cleaning energy threshold requires comprehensive consideration of the material's performance, microstructure, morphological defects, and the effects of laser wavelength and pulse width.

Iji bulie mmetụta nke ihicha laser na akwa igwe, ọ dị mkpa iji nlezianya tụlee ụzọ nhicha laser, ihe nhicha nhicha, ụdị laser, ngbanwe laser, ike, ike, oge ọpịpịa, oge ọpịpị, na akụkụ ihe omume laser. Laser a pịrị apị nwere ike ihichaa corrosion nke carbon steel dị elu. Mgbe efegharị efegharị bụ 1064nm, ikike laser bụ 500W, oge nha ahụ bụ 10kHz, obosara ihu ya bụ 120ns, ihe nhicha dị 60mm / s, ọnụego apịtị bụ 5%. Mmetụta corrosion bụ ihe kachasị mma, ọnụnọ nke oxygen adịghị n'ime laser nhicha nke ahịhịa na-agba agba, akụkụ ndị dị n'akụkụ, ahịrị na isi ihe.
