Review And Prospect Of Laser Cleaning Research Status in Industrial Field

Review and Prospect of Laser Cleaning Research Status in Industrial Field

Although the appearance of laser cleaning can be traced back to the 1960s, the research and application of this innovative cleaning technology has gradually expanded since the 1990s. In the past 20 years, there have been reports on laser cleaning technology at home and abroad. In recent years, it has rapidly become a research hotspot in the field of industrial manufacturing. The research content mainly covers laser cleaning technology, theory, equipment and applications. Domestic laser cleaning equipment The overall level of application and application is far behind that of foreign countries.

In the field of industrial applications, with the rapid development of lasers and the continuous in-depth research on the mechanism of laser cleaning, the surface quality monitoring and characterization methods have become increasingly complete and comprehensive, the surface quality of laser cleaning materials has been improved, and the cleaning accuracy and efficiency have gradually increased. Today, it is a reliable technology capable of cleaning a wide variety of substrate surfaces.

The laser cleaning object is divided into two parts: the base material and the cleaning material. The base material mainly includes steel, light alloy, non-ferrous metal, silicon and composite materials, etc. The cleaning material mainly includes rust, oxide film, paint layer, coating, oil stain and particles Wait. Laser cleaning technology has broad application prospects in the industrial field, including aerospace, automobile, high-speed rail, ship, marine and nuclear power industries.

In terms of theory and technology, although a large number of experiments have been carried out in the research of laser cleaning technology at home and abroad, the theory and mechanism of laser cleaning are not yet perfect. Although researchers have established relevant physical models and made certain assumptions and conditions, these models still have great limitations. To fully reveal and understand the laser cleaning process, a lot of research is still needed, especially in laser and materials Interactions require more consideration.
