Abstract: Laser cleaning can effectively eliminate the impurities and oxides on a metal surface and improve the metal surface quality,exhibiting advantages of zero pollution,negligible damage to the substrate,and high cleaning efficiency.In this study,the application of laser cleaning to metal surface depainting and rust removal,tire mold cleaning,micromechanical cleaning,cultural relic protection,oil removal,and nuclear purification is reviewed.The main problems associated with this field are that the laser cleaning mechanism is not perfect and that the relation between the cleaning and damage thresholds is unclear for different materials.In the future,the cleaning mechanism of different materials should be improved,and the cleaning threshold should be clearly defined to achieve precise and efficient cleaning.

Key words: laser cleaning, metal surface treatment, take off the paint derusting
