Abstract: Laser cleaning has emerged as a new promising technology to challenge the traditional surface preparation method. The PROTAL process coupling an in-situ laser cleaning process to thermal spray in a single step, alleviates some drawbacks of the traditional degreasing and grit-blasting operations, and suppresses the onerous preliminary steps, thus has drawn much attention from industry. This paper introduced the implementation of the PROTAL process, its historical developments as well as the technical principle. The perspective was also presented.
Key words: laser; surface cleanling; thermal spaying
