Abstract: | Paint removal is an important part of steel processing for marine and offshore engineering. For centuries, a blasting techniques
have been widely used for this surface preparation purpose. But conventional blasting always has intrinsic problems, such
as noise, explosion risk, contaminant particles, vibration, and dust. In addition, processing wastes often cause environmental
problems. In recent years, laser cleaning has attracted much research effort for its significant advantages, such as precise
treatment, and high selectivity and flexibility in comparison with conventional cleaning techniques. In the present study,
we use this environmentally friendly technique to overcome the problems of conventional blasting. Processed samples are examined
with optical microscopes and other surface characterization tools. Experimental results show that laser cleaning can be a
good alternative candidate to conventional blasting. |
