Study of the temperature distribution of the substrate in the laser cleaning process

Laser cleaning has become a widely used cleaning technology in recent years. Currently, researchers are mainly engaged in the studies of laser cleaning process parameters. However, when the casing of oil tanks, wind turbines, and electronic equipment are cleaned, the high temperature generated by thermal deposition in the substrates will accelerate the aging of oil, reduce the performance of lubricants, and cause the damage of semiconductor devices. These will indirectly lead to mechanical or electronic failures of the devices and systems. To avoid these adverse effects, it is significant to investigate the temperature distribution of the substrate during the laser cleaning process. In this paper, the results of the temperature distribution measurement of the substrates covered with the rust, cooking oil, industrial lubricants and industrial primer has been presented.
