Laser cleaning is a technology that irradiates the cleaning object with a laser and causes pollutants to leave the substrate surface through thermal vibration, ablation and other processes. The use of laser cleaning technology in the field of ships can reduce the substrate damage of the plate, facilitate the subsequent coating, transformation and other processes of the plate, and improve the service time of the ship. According to the mechanism of laser rust removal layer and the current laser rust removal process on the market, this paper mainly describes the application of laser rust removal technology in ships, as well as the research progress and development trend of laser rust removal and discusses the limitations of laser rust removal technology in the field of ships.
In recent years, the rapid development of nuclear industry has accumulated a large number of radioactive waste, and it is still increasing year by year. At present, the most reasonable way is to cure the radioactive waste for glass first, and then put it into deep underground storage for storage. But there are several mainstream glass curing methods have some problems, so a fast and efficient treatment method is particularly important. In this article, a method of glass curing using ultra-high power laser is proposed. In this article, the borosilicate glass curing body was successfully prepared by using laser, and no simulated analog oxide crystals were precipitated, which preliminarily verified the potential application value of laser sintering in radioactive waste treatment.
