激光清洗在金属表面处理中的应用研究进展

激光清洗可以高效去除金属表面杂质和氧化物，提高表面质量，具有无污染、对基体伤害小、清洗效率高等优点。本文综述了激光清洗在金属表面脱漆除锈、轮胎模具清洗、微型机械清洗、文物保护、去油污以及核净化等方面的应用研究进展，发现目前该领域存在的问题主要是激光清洗的机理、工艺还不够完善，对于不同的材料没有明确清洗阈值和损伤阈值之间的关系，未来应完善不同材料的清洗机制，明确清洗阈值，以实现精密高效清洗。

Advances in the application of laser cleaning to metal surface treatment

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.
