| 摘要: |
| 激光清理（1asercleaning）是近几十年来伴随着激光技术的发展而出现的一项新的表面处理技术。PROTAL （激光辅助热喷涂）工艺引入激光清理技术作为基材的预处理工序与后续的热喷涂工序同步进行，避免了传统的化学清洁和喷砂预处理带来的一些弊端，实现了热喷涂技术的连续生产，因此在工业界受到较大程度的关注。文中介绍了NTPROTAL 工艺的实现手段，发展历程以及相关的技术原理，并展望了未来的技术发展方向。 |

| 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. |
